Almost all the classes have just three damage types as part of their kit.
Exceptions being Warden which have 5 (magic, frost, physical, poison and bleed) and for some reason Necromancer which has all eight (magic, fire, frost, shock, physical, bleed, poison and disease).
And it makes me wonder why?
Doesn't this cause a situation where necromancer have a much harder time getting their abilities to synergize unless you got a set bonus that buffs all the magical or physical elements?
And what makes Necromancer of all classes the master of elements, you'd think Sorcerer would be more versatile?
The question would be the same for warden but least they are slightly less affected.
