It's fairly common that for most low-mid GP guilds, there are a few members who carry the rest of the guild through raids. E.g. for Heroic Rancor, my guild have 3 players who consistently come 1st/2nd/3rd, every time.
Not a criticism - I guarantee we wouldn't finish the raid without them - but it seems (kind of) pointless for players who no longer need the rewards from the raid because they out-level it massively, to then get the rewards for first/second/third. In this case, I feel like an option to forgo those rewards - allowing, say, the person in 3rd to get the rewards for 1st place, and moving the players who fowent their rewards to the bottom of the reward-ladder - would be really beneficial for lower GP/Newer players.
Not sure if this would work in practice, but it just occurred to me and I thought it would be worth at least discussing.
