Please dont take this as a bash, because its not, but no one can really tell you what you would like best at all. Ive also played since release, played every class to at least 60, etc, and every class is a different experience. Also, do you want to focus on PvP or PvE? It sounds kinda harsh, so please dont take it that way, but no one can tell you what you want except you!! I honestly believe any class makeup can work, especially in pvp, as there are very weird combo's that do very well in their own unique way. Just to add in tho, you cant beat 5 mages or 5 shammy's
