Don't get so discouraged man. Most people, even if sounding a bit too critical just want to help you improve it. And I believe you can, in time make it a great campaign.
Anyway to my review:
Chapter 1
- The tips are unnecessary in my opinion. This is an enhanced campaign after all and we should expect new things and surprises.
- Thrall's skillset is a bit all over the place. Moonson and Aid of Lava god are fine since they represent fire and the element of air, in a way. You can make his other 2 skills represent water and earth. That way we have all 4 elements and a nice shaman like skillset, which would fit Thrall.
- Troll headhunters having life drain doesn't make too much sense. An ability that makes them land a critical hit or one that inflicts a damage per second effect would be a good replacement in my opinion.
- Grunts having Thorn aura doesn't make sense.
- The Blood Curling Growl's hotkey is Q
- Remove the random Firelord. Normally if you'll add some easter eggs move them to a location the player can't travel to and can only reveal through abilities like farsight.
- Placing random strong enemies just to make the chapter harder is a bad idea. Instead, you can try and add more areas of exploration to the chapter. Expanding the map size to add a small bandit camp or a cave with dragons in it, or a cave with ghosts in it, that give good rewards, would make people like it a lot more.
- The 3 Little Timmies are unnecessary.
- Giving the hero some kind of undroppable artifact item with a little flavor text on it would be a good idea in my opinion. You make his stronger and give him more of a personality with the backstory written on it. Thrall is a very recognizable hero, but it still wouldn't hurt. Using this method if you're going to add never before seen heroes would really give them a nice boost to their character development.
Chapter 2
- The tips are unnecessary.
- Calling players noobs just insults them and makes them turn off the map.
- Having a random Granite golem and red dragon in your base as an ally doesn't make sense.
- Why does a random rock golem attack your towers and then runs away?
- The same things I said about the strong enemies in chapter 1 can apply here.
- You have the Berserker and burning oil upgrades yet can't train demolishers or troll headhunters
- The pork store is a bit too op. It's like roughly 3 farms + fountain of health at the same time.
- Having 2 pork stores on the other side of the map isn't very practical.
Chapter 3
- Both what I said about the tips and harder enemies from the last 2 chapters can also apply here.
- Ogres attacking you while you have barely prepared yourself is unfair.
- Berserk warriors destroy your army like nothing.
- Changing abilities like that isn't a good idea.
Chapter 4
- The chapter begins with an error message and then black screen
Chapter 5
-Thrall suddenly has his default abilities.
This campaign needs a lot of work. I wouldn't recommend you quit on it. It will become good in the future, once you learn the editor a bit more.
Also, it's very important to test chapters before release. If you can't beat it yourself, no one else will try to.
I even admit i had to cheat a few times.
