Then don't. But if you want to hit an infantry guy before he moves out of the way like I've been doing, it's good for that.
Test it all out in VR with the three Powler main weapons, different targets at different ranges. I personally find it best used with AP while firing at extreme distant vehicles. Just don't stay locked down for very long.
fast moving targets like aircraftsharrasers at medium long range and infantry alongside with extremely far away targets at about 800 meters or targets that pop out for just a little while(kiting) behind cover and stealth flashes
Every time you stand still to take a shot at either a small target or a ranged target. Less lead time=good less drop=good
