Some feedback after playing for a couple of days, though I'm not sure if either of the first two are by design.
One, the blue team can be difficult to see against darker surfaces, especially on indoor maps, where as the reds stand out more against pretty much everything.
Second, despite the Xp being explained as being partially based on performance and teamwork, those have been coming up as 0 for literally every game I've played, usually only getting 1,300 from each game themselves. I can understand if you're trying to cap how fast we can grind these ranks out, but it felt weird that it isn't working as they'd described.
And third, on the emblem maker, the transparent layer isn't coming out transparent. For example, I'm using the headshot on a circle background, I want the bottom jaw gone, and it looks like it under "choose emblem", but in the corner of the screen, I can see that the jaw is black (and we're talking a proper black, darker than even the steel) over the red background. I'm still able to match the color to get the effect I wanted, but that kind of beats the purpose of having a transparent option.
