Auto-fill; Yay or nay?
Personally I don't like it. I can't be the only one.
I'd rather wait an extra 5 minutes, 10 minutes even, than get a roll that I'm no good at. Especially in ranked. You can only dodge once a day without getting too screwed and theres no better way to go on tilt than get a roll you're no good at.
I've played previous season, it's still better than fighting over rolls but that's besides the point. Someone who is auto-filled is more likely to troll you. Not that I would but I've already heard stories of people getting auto-filled in someone else's promos and trolling.
