What do you want to do ingame, do you want to fight close up combat and hit things, do you want to go behind things run in and out stabbing the target, do you want to stand from a distance and just anihilate it without it reaching you do you want to heal and buff everyone or yourself up?
You should decide what you intend to do ingame to help with what you roll, personally i like druids for their versatility, theyre a priest/mage/warrior/rogue all in one. Most complex class to play too, but once you get the hang of it, its really fun.
Look on youtube at some videos, like frost mage/ feral druid/ pally pulling/ mutilate rogue... etc and maybe something will catch your eye that you like.
It doesnt matter what you choose cause if u choose it you should be having fun whilst playing and thats all that counts ;D each class has their pro's and con's and each class is just as balanced as the next... except for pallys ( LOL ).
I have fun on a druid, when i did low level dungeons, i got quick pops almost instant when i could be tank/healer/dps and lead the party. this making it easier to level too.
hope i helped
