You give with one hand and you take with the other.

You offer better rewards in the Events, but then make them even more difficult to win.

A few months back, with a squad of Rares, I was able to complete the Boss Event and win 4SR and 2UR. In the most recent Boss Event, with a squad of UR's and SR's, I could not even win 1SR.

Are you deliberately trying to discourage us and drive us away from the Game?
