Only way to change to a different playstyle is by either making another character or by resetting everything.

Would be really nice though to have an armoury similar to what diablo3 offers, so you can much easier swap around with playstyles and gear. They can even incorporate the cost of those primodial thingies if they want to keep that.

I mean didnt they design the game in such a way that there are no classes, yet why cant we swap playstyles around more easily?

Also changing around ferocity, wisdom, agility and toughness points is really chore espescially when ur higher lvl.
