To everyone using the argument that "omg if they're bot lane and not taking CS and helping get kills they're support!", realise this:
An entire class of champion is becoming unplayable. I've been seeing some ridiculous "support" champions in bot lane. Darius, Fiddlesticks, Jayce... How is it that they do they job of a support (and even an aggressive support like Leona) better than a support champion does? How imbalanced must the INTENDED support champions be to be replaced by pretty much any other champion with CC?
OP didn't mean "shifting away from having a support role", he meant "shifting away from having dedicated, intended support champions.", and it's happening. I haven't seen a Soraka in-game for maybe a month. I haven't seen Sona for even longer. Nobody plays Karma, and I don't think her rework will change that simply because, by the sound of it, they pushed her further in the direction of mage than support. Lulu is still unpopular despite her technically good scaling and ability to be aggressive, because she's still squishy. Janna is only rarely picked. Taric is picked in ranked (or at least in the ~1200-1300 Elo), but he's pretty much the only "clerical" support that IS picked, and only because he serves as a tank/initiator late game, and not as a liability as Soraka, Janna, Sona and Lulu do.
You know there's a problem with support champions when someone would prefer to take a mid champion over an intended support champion. When a support champion is an unattractive pick, Riot has done something too severe to the class as a whole.
