Make Support able to be selected as the only role

Just had a queue with 2 support mains on my team, with 2 autofilled players, one being one of the supports. And he got autofilled mid, which like 3 people had as their secondary, one of which was the other autofilled player. Like what.

This is the product of autofill. It just picks whoever the hell it wants to put in whatever role. Yeah Support might be a bottleneck, but it doesn't hesitate to throw a Support main into their secondary or autofill them if their shield is not up, then autofilling someone else in another game into Support. Quality matchmaking.

Makes no sense. If they want to lower queue times and increase queue health, let Support mains get their primary 100% of the time if they choose. Let them pick a secondary if they want, but also let them not. That way, at least if someone gets autofilled to Support, you can know that there were absolutely no Supports available. Makes no sense to have so many incentives to play Support and construct the entire autofill system BECAUSE of this role, then start autofilling the actual Support mains or throwing them in their secondaries anyway.
