Raid idea for potentially not getting dupe aspects/bad rewards

i thought of an idea that could be nice to be able to reroll your reward pulls in raids, i thought maybe they could do it so like if u stay alive for all 4 challenges (boss and all 3 rooms) u could get +1 reroll so if u dont get anything u want u can just reroll it and its more rewarding to stay alive.

another idea for +1 reroll is for guilds raids like maybe u could get a reward pull if u stay alive for all 4 challenges for guild raids only.

and my last idea is maybe if u use all 3 gambits without dying (or if u just complete a raid with all 3 gambits) u can +1 reroll as a reward for using all 3 gambits, and gives grandmaster a use, honestly just having grandmaster could give +1 reroll anyway.

 

Good ideas, my idea was just to kind of add a system where if you get an aspect that you have maxed out you would get a 'token' and after collecting several of these tokens, you can claim an aspect of your choosing.
