My thoughts on these potions: One, if you're going to run a game with no level cap, something I have never seen anywhere else (which is not to say it doesn't exist), and you're going to have part of that game include pvp between a ridiculously wide range of levels, you'd better give the little guys a way to reach up some. Otherwise it's not very much fun. Really. There have got to be some equalizers around here. These potions don't quite accomplish that, but they help a lot. 

Two, people have put a lot of resources into maximizing this skill, and I'm sick of seeing things given, and then carelessly taken away. Some thought should be given to them. I'm honestly a little offended, on their behalf. 

Everyone has access to the development of the skill, if you want it, figure it out.
