Not sure I ignored anyone? Let me say if you see me on the 360 it is never me I have the old Xbox setup for the Grandkids in the Basement to play their games on.
The only time I have declined a party was recently when working with some new recruits. Power leveling up, Once King Onyx was asked to abandon his Real Life friend and recruit to join some CAG members that needed a 4th and he said I can't bail on this guy. (What says come join our clan like dropping them for better loot).
I Won't drop a potential recruit in the middle of a session to join an established group of CAG guys. They above all should encourage to stay with the new player and bring him into the fold. Am I correct in that thinking?
