No; You know how when you die in a MMO or a Survival Game, resulting in loss of items?
Yeah, and NOW you want to lose skills? Here is a small scenario:
Without your Idea: "I just lost all my loot. F*ck."
With your Idea:
"I basically lost everything I trained for over the course of a few months. I'mma go quit this game."
I think this explains it very well.
