It seems like the game is catered to casual and/or the average Joe's, I suggest this:

During Champ select, there are lights that says:

Tank
Jungle
Support

When one player picks either one of those the light "lights up". Maybe this will make people come up with at least a competitive composition.... MAYBE IT'LL BE A GOOD PSYCHOLOGICAL DETERRENCE TO T@RDS WHO LOCK IN RIGHT? =)

Holy ****, good idea.

I kind if like the idea....but poor delivery.

The problem isn't about seeing if you have all the roles filled out, the problem is most people would rather play a carry instead of a tank/jungle/support.

I've been in so many games where I chose a carry first and then 2 or 3 after me would also choose a carry and then lock in. And since I was the only one not locked in I had to tank. I love tanking but I don't like tanking 10 games in a row :\

Draft mode in normal solves this.

Edit: Kinda solves this. Will make it so people cant just insta lock in atleast.

Are you talking about normal or about ranked
