This may come out to be a bit weird but, we always hear about people coming into Valorant from CSGO so I wondering if anyone has gone from Valorant as their main game into CSGO and how well they did competitively? Personally, I've played...

Basically what the title says. I've seen many people who are very good with the op doing this thing. They shoot and then quickly switch to the knife and then back to the op. What benefits does it have?
