no offense taken, i am know iam on a carebear server, i didnt know about spell/ca and other special rule applied to pvp server, i always tough soe said those were applyed when you were dueling too.
While dueling does use SOME of the rules from the pvp ruleset when you duel, it dosen't use all of them and is considerably different than real pvp. But even still, its a decent idea of how a class would fare in a 1vs1 most of the time given both classes see each other at the same time.
