[2020] The game is awesome.. But devs, could you please put something in place to avoid this kind of unbalanced matches?

We actually have, but it requires players to play enough matches that it can recalculate their skill levels. This should resolve itself over time.

(Also, level isn't an indicator of skill, just playtime, to be fair.)

Edit: Thanks for the reports! We're looking into this, particularly at higher skill levels.
