Idea for reducing (or limiting the frustration of) dodging in ARAM
If you've played much ARAM you'll know that people are very liberal in using dodges in order to avoid a champion or team comp they don't want. This can be really frustrating for those that tough it out and end up going through 5 champ selects trying to get in, losing legitimately good comps and champions they wanted because of these chronic dodgers.
My proposal is to award bonus reroll points to those who do not dodge. If someone else dodges, you get bonus reroll points like you always get after an ARAM match. If you dodge, you lose any bonus points.
Allow bonus points to stack beyond the normal 2 reroll limit, to 3 or 4. This way if someone dodges and you already have 2 normal points the bonus points aren't wasted.
A simpler recommendation I'd like to see happen is just increases the punishment for dodging ARAM, but that is a story for another time.
