At the core of it, for unrated I just want to play 5v5. There is no reward for winning, only for having fun, and 5v4 isn't fun whether it's for or against. If someone abandons, I really just want to start up another game and try again.
There's technically rewards in the form of XP and character contract progressions for unlocks, but I can agree with the general sentiment. We'll hopefully land with a balanced approach that works with both perspectives that are being shared in this thread... or we'll miss the mark entirely, learn from feedback and try again :D (but hopefully more of the former than the later).
