Note we are adjusting the ability as well as the Maxim itself in terms of suppression so you can't nade it.
Currently, the numbers on the ability are being adjusted and nothing is in place but here's some stuff I've been playing to make the ability more useable:
Sustained Fire
-Reload Penalty from 2 to 1.25 during duration.
-Weapon cooldown to 0.5 during the duration.
-Weapon horizontal traverse increased by 1.25 during the ability.
Likely needs more adjustments to somehow put in on par with AP rounds, though that sets the bar very high considering 42 AP rounds increased damage by nearly double and gives you armour penetration. Maybe an accuracy increase to further the role of "Get the hell out of my arc"?
Those sound like promising improvements. The horizontal traverse is interesting because the patch notes made it sound as if the intended purpose of the ability was to focus down a singular unit? Have you considering maybe having the ability increase incremental accuracy or something along those lines so that it functions as a "stop a blob" ability as well? I don't think it has to be on par with AP rounds per se but it needs to be either more responsive or worth the risk of losing your maxim due to the long initial reload.
