New roulette idea: Minimum Item level

[Dewslam]

Would these new roulettes not reward Tomestones?
Or would the others reward less to make room for these new sources of Tomestones?

Otherwise, what would the incentive/reward structure be like?

I'd like to see them reward something other than tomestones, personally, but that's just because it's really, really, easy to cap out on tomestones these days. But otherwise I'm all for adding more roulettes like this or other forms of challenge roulette.
