There will always be complainers no matter how you do the loot distribution.

Every game is the same, player A thinks he's more deserving of the better reward then player B. Player C thinks the reward system is * because the "baddies" are getting the same rewards as him.

if you make the reward all the same, then that removes the motivation to even try your best to win. Everyone will just turn up once for qualifiers and byebye not coming on Saturday.
