What´s Riot´s statement about damage/cdr creep in this game?

Did they say anything at all? Or is this game just "fine" to Riot. I´ve been playing since season 3 with some breaks and can´t remember that burst damage was as huge as these days. Moreover these "complex" assassin gameplay (Talon, Rengar, Kha ect.), which consists of pressing all buttons at the same time to kill a target in 0,1 second from 100 - 0 makes me almost stop playing this game.
