My feedback post in regard to the current state of the assault class.
I generally agree with your points. For me the primary thing that needs to be addressed is how effective the heavy is at close range. The heavy is presumably meant to be a middle distance monster capable of suppressing and holding down corridors and key positions but right now they are most dangerous at point blank range where they can't miss despite their guns inherent inaccuracy. The assault feels like it's intended to have strong versatility throughout the ranges with a particular dominance at close range, so having the heavy be so strong up close is particularly oppressive.
The question is, I guess, how can the heavy have high health, the strongest gun, and a shield, without being broken? Maybe some nerfs around mobility?
In terms of changes to the assault, it would be nice to see the sensor launcher be a little more useful. The outlines are so hard to see right now that it can feel practically worthless. As for buffs to the guns, it may be worth seeing what some of the other assault rifles can do before getting too worried.
