First off don't mention WoW to much around here. You will get laughed out the group. It's basically ignorance because anyone that's raided wow mythic modes know it's a lot more difficult than tank and spank EQ. With that said ...
I would recommend Kittens who say Meow. You can find their guild thread here ...

I don't think they have a level requirement, I could be wrong. But the main thing is they are super friendly, and helpful to new players. Best of luck to you friend!
