I just saw this in-game, but didn't see an official announcement of it so I figured I'd tell everyone else about it to and hope to god that I'm not alone in noticing this just now.
If you press this button

You get this screen

Where you can see how your champion's awakened ability scales with future ranks, signature levels, as well as ascension level. This is something I've wanted in the game for a very long time. I was always really annoyed that you could only see how the signature ability scaled while your champion was unawakened, while you could then only see your current level once you got the champion awakened.
Kabam did add the ability to see how your sig stones affected your champion's sig ability a while back and I don't know if this was something that was added alongside that, and I simply missed it at the time, or if this is something that was introduced in the newest build. But either way, I really like it and wanted to highlight it.
Kabam, you gotta be better at showing your wins. You can't just hide them away in the game and hope that people find them. Be proud and loud when you do stuff like this.
