With the roll-back on roll-based ranks coming along, it's about time we consider removing Auto-Fill in general when it comes to ranked game modes. Ever since the Auto-Fill system came out, people have thrown game simply because they got a role they dont enjoy playing. If this were strictly set on draft and blind games, that would be fine, there's nothing to lose there. But the roll-based ranked system heavily outlined the massive issues Auto-Fill has been causing in ranked for ages now.
There's no logical reason to force people to place a role that they would not enjoy or do well in within a competitive atmosphere such as ranked. It sets people at a disadvantage straight from the get-go for both the player and the team.
Leave the training to Draft pick. We shouldnt have to deal with this sort of issue in Ranked.
