(by “large” I mean in excess of 30-odd players, for those of us lucky enough to have played in really large games)
While cleaning up at Teonn on Sunday, someone (you know who you are, but I ain’t outing you here
) commented that having groups running around together is bad/detrimental/not good (can’t remember the exact words) for the game; I was going to ask about it but we got busy and ran out of time. So I’m opening it up to general discussion, as personally I think having a group of people to run around with and have some camaraderie with is a good thing - however the one making the comment struck me as a perfectly reasonable and intelligent person, who probably had very good reasons for having the opinion they did, and I’m new to large larps and don’t know what I’m talking about 
What are people’s thoughts on groups (for Teonn as an example; Guard, Seafarers, Troupe) in a large LARP? Good idea? Bad idea? Most importantly to this discussion, why?
Please keep this conversation to groups, and refrain from talking about individuals, if at all possible
