Wait, are we arguing that recent releases aren't seeing competitive play?
Quinn
Thresh
Vi
Nami
Zed
Elise
Kha'Zix
Syndra
Rengar
Diana
Out of their last 10 (9 available for tourneys) I count 6 that are regularly picked (Thresh, Vi, Zed, Elise, Khazix, Diana), Rengar who was a constant pick/ban for weeks, and two who have seen competitive play (Nami by the Koreans, Syndra by Link). I'm not sure where this notion that Riot is releasing bad champs comes from, if anything it's on the other end of the spectrum.
