I am an absolute monster with support so far. I have an L86 with a few modifications(100 ammo mag + bipod + muzzle suppressor) and holy shit I am literally carrying games solo.
I run APS(the shield thing), and basically, what I do is, I use it in order to break their ranks then I get behind cover and spray flaming lead down their throats. My highest kill streak so far has been like 14, then I ran out of ammo(both the pistol and the l86)
I really hate playing against snipers but i've learned the maps well enough to know where I should push to make their lives hell. Like, in Metro, I know to push up to the base of the stairs to remove their line of sight(after taking C with the shield)
this game has serious esport potential
