Can someone help me cause I tried the 'equip last used item' in the options but it brings me back to pistol and I still need to scroll down in order to switch back to op after getting a kill. I watched some streamers and they barely switch...

I was in bronze, now gold, and I feel like the higher I go the worse kinda people I meet. The last 5 comp games I've had someone either being blatantly racist/homophobic, hot micing, flaming the other team or just being unnecessarily edgy....
