That just happened to me, I was using berserker for the first time in a long time and all that happened was me being spotted by the one recon constantly no matter where I went or where I hid and chased by two scouts. Whenever I hit one with the net gun the others would show up and light me up or try to knife me.
All in all this wouldn’t Have happened if
A. Only one class could use snipers and the knife didn’t shred my health bar.
B. I was a better berserker (I’m a scout main and am too used to running and jumping a lot)
