Honestly, for me, an event should give everyone the same chance to obtain something that you normally can't get through normal play. Obviously it should still require some effort and not be like a win button. That's why I prefer the puzzle events (despite all the issues they have) over these clicker ones, same chances for everyone, no matter if they just started or already maxed out everything. But thats just my opinion about what an event should be like.
@test_anonAbout those enhancement items (yeah bit late): If you really get 1-2 of those every day, you are lucky in that regard. I have blocked 8 of the 9 enhancement Items by not claiming them and 2 of the lower mojo missions. So only the one I'm currently after is in the pool atm and I'm still haven't gotten it for weeks. So please, just because you (and some people you know) get them, doesn't mean that others have the same experience in that matter.
