So, basically, Tank's healths are low. Some are even lower than Fighters, Assassins, and Mages.
I say, we should raise the main HP about 50 health for each Tank.
But for Zac, we need to raise his 100 for his base. Also, we need to raise that health regen. Like, raise it to 9.125 or somewhere in there. And raise the health regen bonus per level to +0.65.
Or whatever...
