Changed Prereq's. Swapped Combat Casting for Run which given the Movement ability seems quite fitting. Dropped the Knowledge prereq from 6 to 4 so only 1 level of caster is really required, which is good as it's casting is more of a back-seat ability. I'm considering upping the BAB req from 3 to 4 or 5 to compensate. Think so? or is early entry suitable?
Edit: Thanks for the links. I scanned them and quickly realized I am uninterested in the whole "Tier" thing. But at least I now know what people are talking about when the talk about it, so thanks again.
