I see someone using only meta on a shooter as someone who is so untalented naturally they need to have their weapon carry them.
Like, on CoD, in the last 3 games I played (BO6, MWIII, MWII) the meta weapon was always something that had zero fucking recoil by default, so no matter how long it took to kill you could brute force a win on ANY gunfight with sheer accuracy. In MWII it was the TAQ-56, in MWIII it was the MCW, and in BO6 it was the Jackal/AMES. And in BO7 it's the Dravec 45.
Like, are meta abusers so fucking ass that they need a weapon with no actual recoil at all to kill people? To the point they use it for an entire god damn year?? Bro. Every time I used those guns (for the mastery camo) I just felt so absurdly carried it wasn't even funny. I could ego challenge a sniper from 60 meters and still win.
