My Street Brawl games are too easy

My Seven win rate is 124 games won out of 164, a bit more than 75%, which is absurd. I get MVP on most games.

I barely play any standard these days, and I haven't played Seven in standard in years. So I imagine it's something to do with a low mmr/ranking which won't update, mine's around something like emissary 1.

Should I make a post on the official forums? I feel like if someone was in an inverse situation where their skill level is lower than a high standard mmr they'd manage to lock themselves into, it'd really suck for them.
