Losing interest in WoW?

Well, i have a 36 lvl human warrior. All i've done in WoW is questing. Running from place to place, talking with people, Killing certain amounth of monsters. But it got old. I know WoW has waaaaay more things to do. I tried battlegrounds, but all i did was run around getting killed. So can someone tell me some things i can do on WoW, cause i would like to play it, but i dont wanna do HC quest grinding. Im willing to give anything a shot i might wanna try another class, so class and race suggestions are welcome too!
