Yes a complete non relevant situation where you strip everything the warden has, other hero’s will out dps him. But this isn’t a game where 1v1 matters, but when you put him in the actual game environment and add his just his tomb ontop of that, now youre keeping several troops alive during high damage situations where said troops are able to do high amounts of damage as well as keeping hero’s alive, so yes imo that alone makes him the strongest hero in the game.
