What ever happens, Buffer and Healer will always be needed.
With this PVE set up, tankers ain't needed, you can straight delete them, buffers will be fine tanker instead or if really needed, semi healer poko with
thats one of the points if u all want talk about class balance. BUFFER and healer will always be needed. so its not necessary to let them be tanky like they are at the moment. you will need them anyway in your party if u want play the end game content.
I remember how alot people said dbotw had bad balance and was not good enough but i bet you all would wish that the game system would only rough like the original one
with how pve is, even turtles can tank with right items, thats how weak bosses are.
