This is something I have wanted for a bit since 2 dungeons in a roulette is boring (as basically everyone has said in this thread). My only concern is that the amount of Uncapped/Capped tomes you get per dungeon varies, so it is always optimal to get the current 2 dungeons in an expert instead of the previous. If there is no downside to matching the tome rewards for all the Max level dungeons, then that change + merging the 2 roulettes would be awesome.
