I would love to see a relegation system. I do not see, this coming anytime soon.
Waiting for that, the proposals you made are all valid and I would support fixed crowns per Tier and like the way to distribute them.
This would lead to Raptors joining T5 again.
The relegation system would be my dream solution but ya, I just don't think there's the time to code it right now.
Thanks a lot for your feedback, I'd love to face you guys in T5 again!
