I find a mage (60+) to be good at solo questing but in instances it pulls too much aggro and either gives healers a hard time or will die lots.
I have also a lvl 40+ shad priest - healing and support in instances group quests is great but i cant get stuck in and do the damage - also being healer means No.1 target each time and can get frustrating especially in PvP where on my server and Alliance no one ever backs you up and they all run off and do their own thing despite co-ordination attempts. I know the rogue and locks are fantastic in pvp but is this still the case since patch 2.3? If starting a new char for groups and pvp what is currently the best? Thanks
