Mechs are hardly OP currently. Players however make the frequent mistakes of trying to engage them in choke points, not flanking them, or trying to avoid them altogether. Best thing you can do against a Chaser/Brute is close the gap. Easier to avoid their cones, and they have to try and reposition to hit you, which is time and opportunity to attack them. It's not uncommon that I force Chasers to back off of me.

Soaring needs readjustment, definitely. I get they wanted to create a better Battle High/Fever mechanic, but 20% better everything shared across a team only really lends well to imbalanced practices.
