Yeah, I saw that. The MP5 was used close range with 9mm in Warzone, so it will still be the weapon of choice there. But it’s definitely a nerf in regular mp where the 10mm rounds was more used. Basically, in Warzone you want the larger magazine because of the armor and (outside solos) being able to engage more players at the same time.
But the snipers were buffed so maybe we’re back to the HDR/M4A1 combo. Not sure what would replace the Grau for longer automatic battles if you want to continue using an AR/SMG, but maybe the M13 since it’s still a laser.
Edit: on the other hand, I’m watching someone streaming now, and he says he can barely notice any recoil changes to the Grau. So I guess it depends how much the range damage has been nerfed. But it still seems to be extremely powerful.
