u can do it in single player with a bunch of % extra exp gained and a merc to kill monsters in hell. just wondering if u could do that on closed bnet. you still get the stat points and skill points from leveling, you are just a lower level

judging how the fact is that you need over 1450 % exp gained i doubt it'll ever work on closed bnet

Yeah, Blizzard would make sure that something like that wouldn't be possible other wise people would become really godly and you could just become infinately strong...

Why the **** would you ever want to level dowN?

Becuase then you level up again and get stat and skill points.
