I am wondering how viable is it to run a physical-damage party without a dedicated heal/buff/support character (max hydro/geo with a tiny bit of pyro/aero/necro)?

By that i primarily mean a character who maxes out the healing and magical/physical armor restoration as well as brings some buffs and utility spells to the party but without having the intellect/spells to actually do noteworthy magical damage.

So far i am playing only on Classic difficulty but i don't exactly min-max the game (for example i usually ignore crafting and sell all the grenades, crafting materials, most non-heal potions, scrolls, herbs etc...).

I wanted to do a party composed of 4 DPS characters all oriented around physical damage.

But aside from Necromancy and the bit of healing a water Incarnate (summoner) can bring they seem to be desperately missing all the benefits of having a real dedicated heal/buffer character that can debuff enemies and remove negative effects from allies?
