"pay by the number of impressions served"
Huh? You can bid for clicks or even conversions.

You might also consider whether allowing unlimited randomization of creative by advertisers creates incentive problems.

Not familiar with that feature, but I can see how various incentive problems may arise.

You might try other outcomes.
