Where do people group at ~16?

[Weaselblighter]

I've read through a lot of the guides and know how to find general level ranges, but what I'm really after is where folks commonly group for the teens to low 20s on P99? Unrest? Oasis?

I've reached the point on my bard where soloing is getting tougher even with my nifty poking weapon. Not having bind/gate is making me cringe when I have to relocate or even turn in quests. So would like to maybe relocate to a better grouping spot.
