You can thank the end of servers for that. It used to be a group of people all playing on the samer servers and a lot of the time you'd wind up getting to know the group of people. Now with matchmaking there is none of that. You might try a slower paced game like a BR. Still very competitive but it is more strategic in timing and map movement.

Everything with shooters now is twitch reflexes and speeding around catching people by surprise. More so than back in the CSS days and I sucked at CSS. 6 months ago I would have been consistently massacred in a COD multiplayer match because I was so out of practice. It takes me a few weeks to get back to the level of competitive against normal players and much longer for my muscle memory to start working again to the point where I can even begin to defend myself against the sweatlords flying around the maps.
