yeah that's exactly the point, why the fuck are sections this OP?
If you take a moment, you will notice a certain spinning symbol above their heads, it means a doctrinal ability was used and they now deal at least 25% more damage(25% or more DPS to be exact, I've long forgotten in what state this ability is atm) and if you take additional effort, you will see they have bolster upgrade on them, going up against vanila WOUNDED grens and 2 HMGs, 1 was completely off position.
e: And why did right side MG suddenly decided to stop suppressing whole blob and reposition, giving them time to recover?
