I had an idea of 2 loot pools for Crucible
The top 3 on each side get thrown into Pool A
The bottom 3 on each side get thrown into Pool B
Pool A would have advantage of better offerings, that an exotic/legendary engram was in there, not guaranteed but a good chance
Pool B would be lesser, but does have a off chance netting you something real good, but the odds will never be in your favor for grabbing an exotic/legendary engram
This way go ahead an afk, net yourself that uncommon/rare stuff
Participate and at least hit the top 6 and get the nest chance possible
Hell if you are cowards and leave do to getting wrecked the other team will get the huge advantage that all 6 of them will get thrown into Pool A and earn some stuff
You can do Pool A:
Legendary, Rare, Ascendant Materials (Legendary)
Pool B:
Rare, Uncommon, Common, Ascendant Materials (Rare)
Exotic would be the free for all item, can jump into both pools, but A pool would have a nice advantage over Pool B rewards
So Pool B getting an exotic to drop for one of the bottom 6 would be like hitting the lottery almost
Problem with that is when people see they are gonna lose they will just bounce (ala Iron Banner).
Instead I always thought the best performers should get better XP & rep. Loot rewards, unfortunately, would probably have to remain the same. I dont like AFKers either. Granted, to other people maybe im an afker. sometimes when it is hopeless I just turn on TV and half pay attention to Crucible (like trying to grind "you must do 5 skirmish matches")
