I'm in agreement that the mp option is the way to go. Just to clarify though, the x-potion gives 84 dex and lasts 15 seconds, so I'd have to do some tests to see what the exact % increase is. With that said, I'd still wager the casters are getting more of an overall benefit than I would be. What I was kind of looking for was the exact difference, or close to it, to see how big of a difference it is to see if it's worth doing even in non ideal situation.
