No custom abilities, items or units. Undead melee creeps are better than human. There is nothing unique about this map. Bad terrain. Annoying music keeps playing over and over again. Only 12 heroes and they all are probably boring as hell. Lanes are connected with that looooooooooooong empty road that takes like a minute to walk.
I only played it on single player, but i can imagine its absolutely impossible to kill enemy heroes since the there arent custom abilities or powerful items.
Sorry for badly written comment, i'm really tired. Good night ^^
