My only gripe with new champ select is that if you pick support secondary you never get primary.
I am by far better at jungling than anything else. I suck at laning but I'm a half decent support and I can't screw it up as bad. That being said, I don't want to support every game just because I have it as my secondary. Every time I queue it's almost instantaneous and I end up with support. It seems it just looks for whatever role is needed and sticks you there if you have it as one of your preferences. I wouldn't mind it taking a bit more time to see if there is a jungle role available and then putting me as support later, but at this rate I'm just going to put top or mid as my secondary simply because I can't ever jungle if my secondary is support.
tl;dr I don't mind supporting, but I'm going to stop picking it as my secondary if that's all it will ever give me.
EDIT: Okay in some cases you're going to get lucky and get your primary, obviously, so the title isn't completely true. The issue I have is that it doesn't take a moment to try to get me my primary role, it just throws me into a game as support seconds after I Queue.
