It isn't a pet project that one forcefully added to the roadmap, it's part of what an MMO should include in its diverse aspects.
Sounds like a good idea to test, we'll have to check its pros and cons with Dalen and evaluate if it's worth being added:
- High MMR players would gain little if they win and lose much more if they lose, if they fight in the lower bracket.
- Lower MMR players might not want to be queued vs a high MMR enemy, even if high MMR would like to 'risk it'.
- The potential abusive behaviors that are generated by this feature.
