There should be something that appears in the kill feed when a phoenix ult is killed. Usually, the only way to know is by looking at the ults or a teammate comms, which aren't very reliable. It would just be a nice quality of life change.

Had a game go to 21-23 (we clearly lost as the title suggest). I don’t quite understand how -21 is a reasonable amount of rr to lose? I have been losing more games than I’ve won this act by quite a bit so I’m not sure how my mmr could be me...
