I always wait the extra time but 30 minute dodges add up quickly. I would rather just wait in queue for 5-10 minutes extra than take a dodge and re queue in 30 (making 9 players wait an additional 5 each for a new ban and pick lobby). Either I wait alone for 5-10 minutes (without auto fill) for my roll or everyone is held up much longer (with auto fill). Finally If multiple players feel the same way the wait times stack in the case of multiple dodges and new players who got their roll being shifted to auto fill and dodging near infinitely.
I swear I must have close to or over a 50% dodge rate.
