I agree that stamina needs at the very least some form of tweak, as exploring/fighting in the Mountains and Mistlands is really starting to show the issue.

Maybe just letting the jump and different melee weapon skills have a slightly higher % stamina use benefit would do it. Get jump in the 90's and you use about half as much stam as you do currently, same for very high melee weapons skills for combat?

I know its tough to balance without trivializing stmaina as a mechanic, but the current system is incredibly punishing in a hostile vertical environment.
