Ads for new challenges?

Hi,

Don't know if someone came up with this before,bit how about watching ads to get a new quest in the challenge ladder?

I got 100+ badges. Now buying a city badge ans buying a state badge are blocking two quests.

Besides not wasting 200AB for a badge that I won't need anymore, of course I got all badges like two hours around me collected.

So those quests are completely wasted for a player with a certain progress.

Skipping the quest with an ad would be a winwin for both sides...
