destro is still good in pve (he just suck incredible ballz in pvp)
gladi is also good in pve, as equip rises, he gets closer and closer to tyrant and on top equip only reason why tyrant is better than gladi is because of zealot, which he can pop if he aggroes too many mobs or generally for faster cleaning of mobs - all that considering that gladi is better in pvp than tyrant, so seems fair tyrant is better in pve
warlord - sucks compared to others, on official you are able to make trains with them at least, no idea what is different here (i know they have kitty buff there, but that doesnt seem like only problem he has in pve)
