But i am playing as the so called worst class "druid" as a durge.
Uh, in what world is druid the worst class in the game? Buggiest maybe, if you go moon with myrmidon forms, but worst?
Moon druid imho outperforms fighters. People just seem to be sleeping on it.
And spore druid is the ultimate necromancer of the game, just broken. Straight up broken.
Honestly i think you are rigth about it but not because of necromancy. I never played spore but I just found out that he can regenerate the temporary hp. Effective he became for me a troll whit out any downside. This class is insane. I think effectively around the end game its possible to gain like 20+ temporary hp / turn w/o dooing anything. Multiclassing can have even more brutal impact on this class.
