Basic Idea: have a system that allows you to chose between two different attribute allocations. The most basic example would be for arcanist to allow them full INT or MND builds so that a player can both dps or heal without compromising their stats. Other uses would be to full STR for tanks when they go to Frontlines so they aren't wasting the VIT stat in PvP since there's no really way to "aggro" enemies as you can in PvE.

This isn't a vital necessity nor would it be that diverse at this point in the game's development since tanks and arcanist would be the only ones to really benefit at this point. I think it would still be nice to have and it just makes sense for classes like arcanist if they ever decide to do something similar in the future.
