Most people don't care what your class is as much as what your role is. For instance, most servers have a lack of healers and tanks. While at the same time, they have an overabundance of dps, damage classes. Pallies can do any of the 3 depending on the spec you choose. And yes, you will have problems with getting gear in end game raids because of the amount of pallies there are. In case you choose a new class, for dps go hunter, mage, druid, warlock, or rouge. For a tank, druid or warrior. For a healer, go shaman, priest or druid. Don't even ask about death knights, they aren't considered to be real people. F.Y.I. Range DPS is in higher demand than meele.
