I wanted to help out a friend in flex. He is doing a 10 man run, so he asked his leader if I could hop in. The leader refused saying that "it will scale up to 13 players if we invite him". I was just wondering if this is a myth or if it has some ground. Does it really scale on 10, 13, 16 etc? or does it scale per player.
If it does scale in jumps of >1 then its quite a flaw in the system when people don't want to take in an extra friend because it will "make it too hard"
