It has been a must pick since forever
Lets look at the other meta guns of the first months:
R-301= badly nerfed and much harder to control
PK = balanced, nothing drastic has been tweaked about it aside from the mad buff of S3 (which they reverted)
Wingman = nerfed to the ground in every way You can imagine
R-99 = normal mag size increased?
And don't come to me saying "it takes skill"
It takes just a tad bit more of recoil control than the other full autos but is much better in termas of dps, only exeption being the devo, which is a gold weapon
I grabbed the r99 yesterday and melt 2 squads with it and was like
"What the hell is this"
Oh. And everyone on the lobby has one
And yet still people bash on other guns for rising up in the tier list
Hemlock: nerf that shit
G7: nerf that shit
Wingman : vault it
Some people are Even complaining about the L Star
