I do understand that mate, though I think at least a couple of em are actually member rank in BP.
3/4 invites, even if they are top tier warrers shouldn't make a massive difference in a higher opts fight unless it gets down to like 8v8 and they are all still alive. And even then invites tend to take it less seriously than members and spend the round trying to snipe a lot of the time. Tho ofc you guys could run it back with a 'no invite' rule to see for sure, that'd be interesting to see if the outcome changes.
