Warriors are subpar to pretty much all melee in arena atm. They have some minor damage issues (not as bad as people make it out to be), but they suffer from poor mobility (more or less forced to play with holy pala), very poor defensive cooldowns and almost no utility. Ferals are doing quite well with lots of viable comps, high burst, decent sustained damage, incredible defensive options and good utlity (clones, skull bash and stampeding roar). Ferals still get fucked by good wizards though (<3 being a lock), MLS, shatterplay and shadowplay shit pretty hard on them (then again, this is a very good season for wizards).
