I mean it suppresses in 1 volley making it hard to move out of its LOS and then pens on third volley. If you don't know its there you its practically an insta-retreat for anyone in its line of fire.
Not to mention it does a decent amount of damage, costs relatively cheap and is in t0
I'm all for smoke and flank but its field of fire as well makes it hard to move around let alone smoke as it fires outside of its arc due to the arc actually being further forward at the tip of the barrel.
I'd suggest a suppression tone down to reduce the insta pen but keep the long term pin idea in place. Its just so hard to leave it arc.
Allied blobs will overwhelm with said nerf and cause constant lack of early map control which is vital for Ostheer survivability.
