I was going to say something similar, but reading through the OP's post... a Cracked Cluster, sure why not.

I don't think similar rewards to a regular dungeon/trial is too much, no one will do it just for the rewards when a Normal roulette wont chuck them into Titan EX or something. If you help others willingly you deserve a small "thank you". The biggest issue is the mount imo. There are definitely people who are basically using Mentor Roulette as a rare mount farm. I've heard people openly state "I want to unlock Mentor Roulette so I can get the mount".
