Just an idea. What if UE is a use it or lose it scenario? If you don't use certain skills or stats over a set amount of time, you begin to forget that skill, or stat. How realistic is it to just always be a buff mano without ever having to train? This could be a constant thing or maybe come into play once a char has maxed out. It's really just a brainstorm i've had that I think could be interesting when it comes to evolving your character and not feeling stuck in one role.
