okay so i havnt really ever played ally side but decided i would give it a try but not sure which class i should be either human paladin, rogue, warlock, priest or dwarf shammy or worgen druid. out of these im not sure so far, so can u give ur opinion and why dont just say like o cause they are the best. say either cause they level fast or most needed or easiest to use or dont cost alot or what not give me ur opinion and why
