A lot of the reactions in this thread to the TBC server seem overly melodramatic. I personally much prefer MoP pvp to TBC pvp, and those who prefer TBC are most likely playing on Icecrown already. Plus, as I've said before, Frostwolf is and will be the CLEAR choice for English-speaking MoP pvp. If you speak English and want to pvp in MoP, anywhere in the world, Frostwolf is really the only place for you to go. A lot of people look back fondly on 5.4.8 pvp, and, that being the case, there will always be a place for Frostwolf.
As far as Frostwolf not getting fixes, for the pvp I enjoy, I honestly think the class abilities are in pretty good shape as it is. If they could fix those stupid bugged trinkets like kidnapped puppy and voodoo gnome that would get rid of the one glaring issue I see from doing bgs here.
