Shorter champ select intervals?

I feel that the champion select process takes too much time out of the overall match, especially when there is a chain of dodges in a row. Even just one dodge partway through the selection process results in an average wait of probably ~15 minutes. Out of a 30-45 minute game this is quite a significant portion of time spent waiting.

I feel like part of the issue could be resolved by decreasing the time allowed for choices to be made, 30 seconds is quite long.

Additionally, many of the dodges happen probably because people had tabbed out to a different window, and were unaware it was their turn to ban. Shorter selection times of, say, 15-20 seconds might help retain attention and prevent these dodges.
