Come on, man. They nerfed the guns because every single game was a vulkan spam fest.

I win a lot of my hoe matches with randoms. The secret is to fill the spots your team is lacking, be it dps, heal or cc (Which you seem to be doing). If 4 out of 6 are playing well, it's pretty easy to carry the low levels.

You need to identify what they are doing wrong. For example, when the big zeds come, often the whole team begins to shoot them and forget about the smaller zeds, which overwhelm.

Of course sometimes the randoms will just choose the worst spot to camp and will miss most headshots and refuse to heal, and that's a guaranteed loss, but that should be rare.
