I read a lot of guides when I'm gearing up my toons in order to maximize damage or healing or whatever I happen to be doing then. Invariably, the guides are written for the opposite faction from what I want at that moment. This is from a 2012 Dulfy post, but it's still very helpful if you're looking at a guide and need to translate from 'Imp' to 'Pub' or vice versa.
