Is there even any CLASS that sucks in PVP in WoW? Maybe some specs, but not an entire class. The developers design the games to be balanced, whether it's WoW or WAR. What's considered the current best class is usually only temporary. There's a constant rebalancing due to new skills and items in MMOs coming into play all the time. If WAR is worth playing at all, you should be able to do well as any class, same as WoW.
