Hey there, I know I've already approved this map (I didn't even have to look at it, I just knew it was approvable) and found a few things that were rather interesting:
First of all: the item system is a bit bugged... it works, but if you pick an item that does not belong to you and you move right after you picked it up (only a fraction of a second between picking it up and moving), then the item doesn't drop and you have an item that you shouldn't be able to pick up.
I believe this is because there are 2 item systems at work: 1 to put it in the correct slot and the other to check if the unit is able to wear it in the first place.
I think it's best if the class-trigger would have the highest priority (if he is able to wear it, THEN run the trigger that puts it in the correct item slot).
For some reason, my friend also started lagging extremely hard (FPS even dropped to 2 in the summoner area), but this may have to do with his PC (he has a good PC, but... there are just some problems with it from time to time

).
My FPS dropped from 64 to 58 though :/ (okay, not extreme, but a permanent drop in FPS usually means something).
Now 2 minor things: inside the dungeon, there was a place where you could go off the side (not very far, but it's still a bug) and there's a typo in the first spell of the witchdoctor (the one that reduces armor): in the learn tooltip, it says "und" instead of "and" (very good job on translating it though, vengeancekael!).
Other than that, I haven't got any remarks... good map, pretty entertaining.
At the end, I wanted to kill the remaining mobs, but couldn't, but that's more a positive point than a negative one

(since I wanted to keep playing).
I hope to see those bugs fixed soon, but for now I'll give this map a full 3/5 (the item system is quite a major flaw in the game, it was almost impossible to get potions since the inventory is full and other minor glitches).
The terrain is great though, I love it.
@Riot: hm, I found the balancing quite well actually xD
Me and my friend completed the map without too much problems (we died a few times, but who doesn't if you've got 2 mages and not a single tanker or even melee hero?)
Of course, compared to CloudWolf's diablo, this one isn't that great, but as a moderator, I don't compare maps - a map should be good on it's own, not in comparison to other maps (I think I've said this before quite a lot

).
Edit: I also removed Sinder's rating (no valid reason).
And vengeancekael: please refrain from giving a map you worked on a 5/5 ^^
