I've played the map for quite a time and can go on with a few suggestions and report a few bugs. I'll begin with bugs, though.
Bugs list I've spotted:
1:The 10th reborn STR guy can't go patrol - his AOE passive skill bugs it, so you cannot even go attack move!
2:All the clone/illusion skills works like in normal warcraft 3, therefore it dispells all buffs and debuffs - even the battle exp % bonus, which SUCKS. Please, change it or make the exp % bonus triggered, and not a buff that may be dispelled.
3:Some of the bosses are nearly unbeatable, as mobs near them STUN you and spawn WAAAAAAAAAAAAAAAAAY too close to the boss. It makes it totally a stunfest without any chance to kill the boss on the first time - you gotta be REALLY lucky to do it. (Please, change the freaking stunning mobs! It's retarded.)
4.The bag that you open by your hero skill doesn't work, which sucks, cause a bonus inventory/autoteleporting bag would be awesome - you can't always carry things as you usually have 3x attack speed glove+boots+armor+weapon.
1:Actually, only strenght heroes are good in this map - the only exception to that is the no-reborn archer (due to multishot) and the first-reborn mage (same thing, but also got heal and divine shield which makes his game pretty easy on beginning, but BAD later). You gotta make the heroes more useful, as to deal damage on eg. mage you HAVE TO max int and while doing it, your hero is SO DAMN WEAK that he can't even survive the stunning mobs later!
2:While speaking about heroes, begin with the 10reborn ones. The AGI guy sucks badly, he's even worse than 1rebirth orc guy! Not even speaking about the summoner. Tell me, why the hell summoner has just ONE summon that goes off almost immideatly? In my opinion, the hero should be more like final fantasy style - has ONLY summons, but a variety of them and would not be able to summon more than 2-3 at a time while having like 5-6of them. That would make summoner strong and a fun class to play, while not making him too op. Oh, and the summons should be permanent, or at least till they die. It's not fun to click a skill every a few seconds just to add two summons to your group. Especially that this skill's cooldown is almost same as the summons duration!
3.CHANGE THE STUNNING MOBS! That's the most important reason for the 'endgame' for being damn hard! Especially the range stunning mobs are a bullshit. How the hell are you supposed to kill/dodge 5mobs that permanently stun you, AND THEY GOT RANGE!
4.Do something about items in inventory! The only way you can not suck in this game is to take an str hero (after a few reborn of course cause the best hero for reborns 1-10 is the Fenix Mage), go max str and get boots+best armor+best weapon you can+3x best gloves you can. No other way around, cause you will suck. That ain't good, especially because armor adds JUST armor and weapon adds JUST damage. Strenght heroes are great with it - they have a huge pool of health by themselves so they don't really need more HP, but what about agi or int guys? The agi is bad, cause he doesn't have even HALF the hp he needs but got a lots of armor, which doesn't really give anything if you can't even survive 2-3attacks! The worst thing is about the INT guys though - they don't have neither healthpoints nor armor, making them utterly weak. And if you want to remove attack speed from agi, just set every hero strenght-based and change mana costs or something like that. Make the game BALANCED AND FUN!
To sum up fourth point: You either need to change armor/weapon items to also give bonus stats (which would be best) or BALANCE the stats and change pretty much every hero's main attribute to strenght.
5.Change the mob's aggro - sometimes you aggro the boss by mistake, and he just wipes you easily. Especially on the higher level locations.
These are just a few of my suggestions. I'm already on 25th reborn and tried the AGI Legendary hero. Yeah, he sucks cause of his healthpool and worse skills than the STR guy! It doesn't say anything good on the map when endgame is unbalanced.
Oh, and the colors are done on purpose but no idea if I colored all the stats.
