It won't ever be vanilla again so if thats what your expecting the best advice I can give (in a non mean way) is don't bother.
However it has been redesigned, questing streamlined and made more fun, graphics improved, the world improved and changed a lot and ultimately the experience has been vastly improved.
All I would say is give it a shot. Defias Brotherhood RpPvP realm on horde side and just join in with a nice friendly (and extremely active) guild and see how you take a shining to the game!
Well to be honest, I think it's a completely different game from vanilla now so I think it warrants me going back into the game and giving it another shot as I used to love it.
I can't play Darkfall at the moment because it's too cold to aim, just want to enjoy the PvE again, as I used to love doing it.
