Even though more people might need AK or WP, having the roulette the way it is is killing incentive if people like myself keep getting the same dungeon.

I propose a solution: Have the game keep track of your consecutive wins done in expert roulette for the week. It would only keep track of the win you got that rewards you with the daily bonus. Then, for every repeat that week, poetics reward increases by 10. This resets at the regular time each week. You might still only get AK, but the more you run it, the fewer times you have to do roulette to cap poetics.
