Skill tree which active only when in selected class.

At the moment, all skills are passive unless on conditions.

I'm suggesting a class selection passive skill tree which conditions are on matching class selection.

Class selection being changeable off combat and conditions meeting sleeping on bed.
Ie, selecting tank class, will enable passive for tank passive tree.

Allowing players to role play as a tank. And allows for some negative stats modifiers.
ie, massive healt boost but reduce movement speed.

Ie,
if class =='Tank', do conditions 'massive health boost', else end.
