I truly believe FNS can shit on KC with a team with 4 irons alongside him.
Scream and nivera can literally 2v5 fns+ 5 diamonds, simply because it will actually be a 2v1 since diamonds are fucking trash in terms of aiming, any random low elo imm3 ranked player will have 2+ kd in dia if he tries, and low imm3 is way below even the bottom of rad in terms of mechanics, scream and nivera are mechanically very solid.
