Tanks/Healers that queue and decline repeatedly

[Saevel]

heres a break down of numbers from what I typed for example boss 1 would drop 50 and 15. bosses 2 and 3 would then drop the same amount.

That'd be fine, as long as the reward is accrued and then paid out on completing the dungeon. Otherwise I think you'll see some people dropping after the first boss.
