All my hunter needs now is +2 scope, so I'm starting to think about a new toon. I wanna roll AP horde, and I'm thinking either FC or heals. So what do you (horde AP community) need/want more of? Specify class/specc/role please

Try a lock/druid/mage/priest. They don't seem to be played as much as other classes.
Locks are highly effective despite the negative stereotype surrounding them, don't believe me I got screenshots to prove it.
Druids are probably the best FCs though for obvious reasons (speed, hurr durr).
And mage is just a blast (arcane blast). Probably my favorite class at 20 for the insane burst, polymorph, slows, aoe, blink, etc. Just get used to dying a lot or setting to /follow on a healer, we're so SQUISHY!
And dont be afraid to play frost. I've seen frost mages from AP keep 5+ ppl off of me across midfield without any sort of pressure(of course with me playing properly) from the other team. Frost Mages make the best support class for FCs when needed to get across midfield; especially a Druid FC. And as Fourtwennay said, dont get bummed out if u die a lot. Ur squishy but mages(especially frost mages) have some of the most amazing utilties available in the F2P bracket.
hmmm, FC druids are always fun.
unless for premades where your main purpose IS as a support class.
