Lvl 20-ish Grouping Areas?
 

Anyone have recommendations for an upper-teens/low twenties group to go for fun leveling? Interesting loot is a bonus :)

Mistmoore, SolA, Upper Guk, Runnyeye, Highkeep. Quite a few options once you hit 20.
I would recommend 23-24 for highkeep though. Excellent exp there.

For a man like you I would recommend the land crab. Excellent seafood.

Picked made a great list. SolA is a cool zone with some great loot opportunities. It can carry you and your group for quite a while as it increases in difficulty once you enter the castle.
Mistmoore is another good zone for XP. I always enjoyed doing Unrest at around your level. You can do the Fireplace as a camp spot and get some good XP and decent loot.

Don't forget to consider The Crypt of Dalnir in Kunark as well. There are some great zones in Kunark which people rarely go to. Mines of Nurga and Temple Droga also come to mind in the 30's. They are challenging but neat zones.

I have always enjoyed Najena

Thanks for all the great replies. Right now we're grouping at Mistmoore, it's great xp but a bit crowded. Hoping to try our SolA from what you guys have said.
