It is just a comfort thing since we all know who is who and how they play at this point.
Just join our chats and run with us some time. I normally forget who is who, so I just receive an invite out the blue from someone I don't remember, I more than likely won't answer though
One of those the more they see you and talk to you, the more they remember who you are and invite to run with them type of things.
If you are of level, decently equipped and know what you are doing or can learn quickly and cool to cut up with, then I don't mind anyone for the most part.
