I have a mage at 60 and a cleric and rogue in the mid 50s. What specs would you say are good solo queue specs? (If you say warrior, I best get my butt leveling!) It gets incredibly frustrating if I dont always queue as a healer, as the healing seems a bit sparse in general (EU servers)

I tried a bard/tact spec last night and that seemed pretty good but wanted some opinions from the more seasoned players.
