You've already made an identical thread about this - please don't spam it all over the dungeon forum. In addition, my previous quote still applies. I wouldn't ever consider joining someone saying 'friendly' in one sentence and being openly unfriendly in another.

Free advice:
If you're hoping to start your own 'healthy community', it might help if you didn't start by throwing out a sweeping-generalization as part of your recruitment attempt. Be they raiders, casuals, sprouts or hardcore - not all are friendly nor unfriendly. People will be people in every demographic. I've met just as many toxic sprouts as I have toxic elite and just as many on the opposite end of the spectrum (nice and/or helpful folk, regardless of experience), regardless of whether I was levelling, doing dungeons, or taking on savage content for the first time.
