Any Advice on Illidan Mission 6 would be much appreciated.
Yes, I am snatching away all heals before illidan gets them.
Yes, I am maximizing my Mana use before it is inevidibly drained by mana burn.
Yes, I have tried switching out Items to have more armor + Lifesteal.
No, I do not have the Shield that gives +5 armor and anti-pierce damage
No, I do not have the gem that gives +300 life and regen.
And, despite what the walkthrough video up there shoes, Illidan apsolutely never aggros the crystal golem.
My skill setup is Q 4, W 4, E 0, R 2. Managain passive 2.
In the end, even if I micro everything as much as I can, Illidans final form just does too much damage for my mana-depleeted half-lifepoint malfurion, even when i get lucky with crystal golems bash.
If noone knows a way for me to succeed here, I guess that's where the campaign end for me.
P.s.: Like the Campaign. Much work was put into this, as with the previous 4 campaigns. Liked the Human Campaign and the Orc Campaign, skipped one mission in Human, none in Orc. Hated the Undead Campaign and skipped the last third of it entirely, except the one where you explore Dalaran, even found the secret with Uthers ghost key leading to a secret room, by getting the gem of True Sight in a trap room. Found this campaign to be poorly balanced and stacked against you in many ways. This one (malfurions quest) was quite delightful so far, but this roadblock seems untakable. Big props on it regardless. Seeya
EDIT (of course there is one... xd ^^'):
So, I made it, and I made it rather easily, and I made it in like the least time possible, as far as the fight was concerned. Contrary to a certain walkthrough I didn't spend 25 minutes dancing around the battlefield trying to get regenas flowing. 2 things came to my aid. a) The gem that gives +300 health and 4(!) Health Regeneration is actually on this level. It was the one item I missed. b) I still had around 700 gold over from the optional quest with the corrupted Ancients, so I backtracked all the way back there (which is how I ended up noticing a patch of black map conceiling an archway to get the gem), and went to the vendor on the west most spot on the map and bought 2 books (only needed 1) to reset my skillpoints. I ditched the Q skill (Fire Stream or smth), and got Level 4 Fireshield instead, the rest was the same as before. This fight almost melts to the fireshield. Bigtime. Although the Gem probably did its part greatly. I won the fight letting Illidan capture 1 mana-rune, getting all others, with 300 health remaining, an active fireshield on both me and my golem and no mana. Yes, I stood right next to the transformed illidan in the last phase to keep doing fireshield damage. The fight took less than 5 minutes. In which Illidan didn't aggro the Golem at all, except when my character wasn't there for a moment to sweep away some naga.
I had a bunch of Items I could've optionally used, but I ended up just switching out the Staff of Corruption (+8 Int, summon corrupted treant) for the Gem in my Int-Stat based build, I only had 11 +1.5 (+5 Agi stat) Armor and a 1825 lifepoints with some 1100ish Mana. I did use the Life-Steal Blade, and my attack stat was amplified by around +35, with my Int stat having a +29. I could've switched things around to have over 20 Armor, at the cost of some Attack stat, resulting in less Life-Steal, but it's difficult to tell what the best setup here would be. But bottom line, get Fireshield, and get the Gem that is luckily on this very level, and any not completely ineffective build (having all the auras you can aquire in form of items wont help in this fight much, but I did use the legendary that gave +5 stats and Trueshot aura, as that also increases my damage output), should get you there, barring some failures to potential mistakes or offscreen health rune spawns. Always cast your fireshield before you start engaging with illidan, recast it before it vanishes, summon the golem as soon as possible, but not before you can focus on illidan. I actually went out of my way to defeat the second to last batch of naga despite illidan using firerain to bring me from 1500 to 1000 lifepoints, and it worked out for me. getting them to attack your golem, getting the two runes, and getting in between the naga and illidan to start channeling your ultimate might be the more effective approach.
Note to the dev: Either rebalance this fight to be more forgiving to varying builds, or add a vendor somehow nearby that can sell you the re-skill, instead of having me run 12 minutes around (if I still have the gold, which wouldnt be guranteed, but I could still sell some stuff I guess) to reskill into fireshield.
Or at least add an easily visible box that holds the damn thing. Would also serve as a hint to the player that this fight is not balanced around all builds you could make.
Even worst case scenarios, like wasting the book, would be mitigated by it's appearance in the very last stretch of the map (you do have a save from before, right?). Still would feel bad for the poor guy who makes it a point to have only one save file, only to find that he screwed himself by wasting said book and then saving before the fight. So keep the far-away option enabled up there in the corrupted ancients map as well, I'd say.
Anything nice I said about your campaign(s) is still true

Moving on..
