My english isn't good, and
Championfighter25 helps me so much in this regard and dedicates his time for me, and I know that there still are things to fix in the grammar, so there is no need to repeat it over and over again.
Uhm... Your campaign description says that "the grammar is fixed" - this implies that the fixing process was finished. Thus, people probably just understand that what they see is the final version of the script and they point out that it still needs work.
I'd suggest updating the campaign description to something like: "The grammar is BEING fixed", which translates to - "I am/We are currently in the process of fixing the grammar, so what you see in the game right now is not how it's going to be".

I'm not going to write a wall-of-text review (edit: I've SO failed at that, hahahaha), but - so far - my early impressions (after finishing about half of the campaign):
1) Terraining - considering this is a campaign and not a dedicated terrain showcase, the terrain in this project is for the most part very well done. The overall design is interesting and varied, the usage of textures and doodads is really good and the practicality... well, there are a few spots where paths are a bit too narrow or the terrain otherwise obstructs the play area, but nothing that would piss me off too much. Overall I think the author put in a great deal of time and effort into crafting a detailed and interesting terrain, which is why I will rate this aspect as high as 4,5/5.
2) Story & writing - the campaign could definetely use some more world building. What I mean by that is that it would be nice to learn more than just the basic context of each mission, for instance - which Admiral (I assume Proudmoore) is chasing the orcs, how did the Trolls end up on the Isles, what was the Death Revenant in Chapter III, etc. Moreover, from what I've seen so far, the main plot is a bit basic and straight-forward, but still decently enjoyable, so I won't really complain on that front.
Character development seems to be a bit lacking too - other than Trall and occasionally Grom, the vast majority of characters serve as exposition tools and thus come across as pretty bland, for instance - Sen'jin or Samuro, who in my experience never do or say anything that would build them up as characters. Moreover, there's quite a bit of weird moments - for instance Thrall just assumes that the Trolls want to be a part of the Horde and enlists them without asking only to later abandon Rokhan and his decimated clansmen on an island that was once before attacked by the humans, despite the trolls wanting to go with him. It makes no sense. There's also some sensing, petty Mak'gora in the first mission, Drek'thar who somehow got to Kalimdor before everyone else to establish a foothold and more. So yeah, overall the story is kinda meh.
As for writing... It needs help. Don't get me wrong, you can totally understand what the characters mean, but there's quite a lot of mistakes or stylistically questionable sentences. That, however, I can forgive. Not everyone is a native English speaker. What I can't forgive though is that there are also some lines that contain silly mistakes (missing dots or whatever) that came not from the lack of knowledge, but the lack of will to proofread the scrip. There's not a lot of them, but it happens. So, ultimately I have to say that while this is in no way, shape or form the worst writing that I have ever seen, nor does it come close to it for that matter, it does need some work.
Overall, I'd rate the Story & Writing section... well, sadly just 2/5 and that is still me being rather generous, because I honestly like this project.
3) Custom content - contrary to
@deepstrasz, I won't complain that the author went with the standard tech-tree. To me it makes sense within the context of this project. There's also quite a bit of custom assets, though - as
@deepstrasz said, the campaign could use a bit more of custom units, especially in the "player-controlled" area. But still, there's a decent amount of custom assets and from my experience they all work. As for the Grom model - I do like it. Yes, it does look better than other models and it is kinda weird that a side-kick gets a better looking model than the main hero, but you can't have everything. And while on the topic, so far Thrall also seems to be the most boring hero in terms of abilities, at least in my opinion, which is even more weird considering that he is the protagonist of the whole campaign. But well...
Anywho, as for custom data itself... Yes, most of it is a simple edit or copy of existing stuff, but at least to me it gave an illusion of freshness. Granted, I don't play W3 a lot these days, so I may be less fatigued with the original abilities and such. Anyway, there are also a couple of pretty unique spells imported from the Hive (I guess), which is a major plus in my book. So, overall - the custom data in this campaign is maybe not very impressive, but totally fine. My rating: 3,5/5.
4) Gameplay - it could really use a higher difficulty settings, because so far it's rather and I imagine some people would love a little more challenge. Other than that... Well, there were some moments that I didn't like - for instance not being able to kill the enemy trolls in chapter 2 (or otherwise stop them from attacking) or pretty much every boss fight, but overall the gameplay is really enjoyable, the maps and objectives are fairly varied and even though it's just your regular W3 gameplay, I've grown to actually really like it. To me a 4/5 rating is justified.
5) Execution - I haven't found any huge bugs, but... the lack of polish is apparent. Missing loading screens, unskippable cinematics, weird use of text messages and the quest log (i.e no "undiscovered quests), unexplained pathing blockers, units teleporting, cinematics showing sides of the screen, etc. There's quite a bit of those. Do they make me enjoy the campaign less? Well, not really (bar the unskippable cinematics), but they exist and thus for the purpose of this review I just have to mention them. Other than that, the triggering is fairly standard and it just works (for the most part), so obviously no issues here. Overall I'm going to give it a 2.5/5 rating right now, but this could easily go higher when the author applies some extra polish.
---
So, to summarize - this is a very promising project. Granted the writing (and not just the grammar!!!) is improved and the author polishes the execution, we're looking at a campaign that to me could definetely end up as something that I could safely recommend to anyone loving the core W3 RTS gameplay and wanting some more Orc action. Right now, sadly, I see this project as a little more of a work in progress and I genuinely want to see the author being as commited to improving as he appears in this thread. I'll keep a look out and update my score first once I'm done playing and most likely revisit the project in a few months to see how it has evolved
For now - we have 16,5 score in 5 categories, which gives us a 3,3 average, i.e. 3/5 stars rating.
P.S. If the author is interested to hear the details of my critique, I'm of course ready to elaborate and provide specifics, but due to the already considerable length of this review and the fact that it's generally more of a general-impressions kind of thing, I'm going to abstain from doing it for now.

Even though the mission's goal is to have all heroes survive the attack, killing Thrall didn't make the mission fail. I still had other heroes with which I killed the Infernos, the Warsong guards and Grom
