I used to play a lot in S5 and coming back to rank I've noticed now if I don't "Lock-In" during the champion selection screen, it counts as a leave and I get banned.
This is not obvious when you're in ranked when you have a champion selected and you think you're okay. Can you at least make the screen do something crazy like start blowing up and saying "HEY YOU'RE GOING TO BE KICKED IF YOU DON'T LOCK IN" or something like that? I don't want to be penalized for not locking in when I already selected my champion. I just don't see any reason for it when I can select my champion early on.
If this isn't possible, could someone provide some actual reasoning why you have to lock in at least? I feel like such a dickhead when I get kicked and I'm waiting there like "ugh why did someone leave the selection" and then realize it was me.
