Extend Pick Timers
I know a lot of people are getting a little upset with how long champ select is taking, but perhaps extending the timers as you get nearer to the last pick could help stop accidental dodges. I for one have accidentally dodged a fair share of game just by looking for the right champion to pick. Especially when jungler, trying to put that last puzzle piece for your comp into place, only to find yourself on the last few seconds with no idea what to pick.
EDIT: shortly after posting this, I "lost" a promo game due to it -_-
