Pure career achievements (Worlds first) seem to have been the standard so far, but it's understandable that people are confused about Bdd getting it — LCK just handed it out however they felt like.
But getting mad about Doran not winning Top of the Year doesn't make sense. Kiin played way better in-game this season than last year, and career-wise, he even won EWC this time. You can't compare Doran to last year's Zeus when Kiin's (GEN) career this season was just that much bigger.
