Block skill tree, really do sknow switchers? they can be sub and dom or depravade depend on their temper or if they are in mood they go with sub or dom and so on.
I like diversity. If it lock other I just stop playing, it really lock the whole diverity and possibility. Why blocking a skill tree when you can explore. Otherwise it like been forced into one path insteead explore everything. Diveryty like in real life is mutual. the persone ain't write on papre naightetheir charcter. The nonotech are made to make it swichers, yu want be dominant or sub depend on your preference or kiny fethishes, you want be dom and act as dom you can or sub if you into submision. Diversity, dude and possibiltyof choise. Blocking a tree you can't pretend to say no to something you don't like. Choice are mad e to make something different depend on mission or quest. Why locking them it would kill all diversity and mitych who can change apperonce.
