Why would u even use gld in the first place. The gun is great.

Yeah I was surprised but the streamers I watched, whom are all super unicums, used a gld and it kind of made me think why they picked that.

It's because the tank is really, really slow. When your DPM is shit and all your damage comes out of engagements rather than cleanup you really can't afford to miss shots. You're going to outpaced by your entire team in both DPM and positioning after the choke points are broken, so the GLD is there just for people who don't want to risk losing out on damage whenever they can get it. 

It's obviously wrong though, but it's a fairly legitimate idea. Vents won't give you much either since final acc is already good and the biggest reason for it would honestly be for the small mobility boost it'd give rather than gun related ones. If you run optics on it there's at least a chance that you can find people at range and rack up some cleanup that way. If your aim is good then optics should generally work better since your vision is something you can play on very well with the high base VR. It's a very good equipment piece on something that is generally too slow to play on mobility. This lets you play on range a little bit better and for a tank that sucks at moving it's a pretty big plus. That's how I see it.
