Late to the topic... but I agree with Soggy. We don't have "target" wonders as he describes, but we do have kp chains & trades/deals going on regularly. If someone has filled it through trades only, he might only have 3 slots filled. Now the real question is, how many more slots are left? As it gets close to full, we want to maximize the kp instants that get handed out to the FS, so we will divide the kp remaining by the chests remaining and tell everyone that they have a shot at some kp instants if they help fill the AW. It keeps non-FS members out, forces Inno to give away more kp instants, and gets our FS members a few more kp.
Right now, we either go to Gamers Gems or we toss a kp in to see if there is another chest left. It would be nice if the AW screen would have that info instead.
I don't see why anyone has an issue with us trying to get Inno to give out more kp instants in this use case. I am definitely voting for this idea. I hope it hits 20+ so we can see it forwarded on to the devs. More information in-game is always welcome.
