level up a healer or tell him to play a healer just for the story dungeons (after lvl 30 it should be easier because then tanks will be the high demand role)

there's PLENTY of people doing the lowbie runs still. I queue for the lowbie dungeons daily because i'm still trying to get the mage headpiece. I queue as CON and always get insta-pops.


on top of that, I'm afraid you may actually be hindering yourself if you're 'spamming' for group members. 5-10 min may not seem like much, but most people will be in a zone for longer than that, doing leves, collecting materials and the likes. they may see nothing but your LFG for quite a while. I can only talk about myself here, but every time I think 'well when i'm done with this leve I'll ask him if he still needs someone' I have long since lost that thought because for the remainer of the leve I've seen the LFG shout 10 more times.

I'm also wondering if you just keep shouting, or if you're shouting while being queued.
