Perhaps this has been discussed before, but I still don't understand why a gear lockout wouldn't solve the issue. It would allow people to go through and help their FC members through turns but they'd only have the chance to roll on loot once per week (just like it is now). In theory this is no different than those FC members running with PUGs because they weren't able to do it with their own FC, so it's not really like people are able to gear faster than they would have been able to. Additionally, it would help people get more practice at turns in the same manner that the OP described.

Surely it can't be that hard to implement a system like this, right?
