Level 0 dodge should cost 50% more stamina usage than current and at level 100 dodge you would use 10% less.

In addition to that the i-frames you get for dodge rolling should start at .05s. and go all the way up to .1s at level 100.

Level 0 dodge should make your character essentially roll in place when he does the dodge and at level 100 dodge you roll .5m.

Just kidding. I like the dodge system the way it is. Please don't add another combat system element I have to level
