The problem is after that you cannot change the loot at all, it gets stuck, even the adena distribution bugs out. Auto cancels out everything when you try to change. I mean I would be fine with just the first hit system, but if someone screws up and you want to change it - that is it you are done, can't do it...
Also as long as other pt's hit first not the CC leader, the whole drops goes all random, so that is fine as long as people communicate or no greedy CC leaders
