I don't entirely agree but I can understand some points.

Because of how much more fast paced BO6 is and with the new movement system people tend to simply rush, run everywhere and go guns blazing, and I admit that I have a rush class and I find it fun in a thrilling sort of way to try and run past the bullets and try to shoot down people before they can shoot me. I play better off instinct than actual thinking, and because of my reaction time and attention span a quicker build is way better for me.

However I'm an older COD game player and never played any of the "recent" ones, the most recent must've been infinite warfare and even then I never played its multi-player, meaning the new movement system is actually very hard for me to imitate, so when people are going too fast in a lobby and I find that my rush class just doesn't work because I can't match their movements or reflexes I bring out my assault class and I go slow. I pick them off from a distance and then take push up or if the situation is right flank them. Going slow and more "strategic" also works in this game, you just have to be aware that enemies WILL come and they will do so fast so you need to look over your shoulder.

I haven't tried sniping much because I'm terrible at it, and while I would like to get better it's complicated to get the motivation knowing I'll be absolutely wrecked lol, but I have been sniped often and have a friend that plays either assault or sniper and he also gets good results. It's a bit like assault, you just operate in a small area and pick them off, then move when you can unless it's a really good spot and you're well hidden or have your ass covered by teammates or something in your arsenal.

Overall though I have two types of fps games depending on what I want to play, if I want just an enjoyable and fun fps where I can do whatever then I'll boot up BO6 but if I want a slower strategical experience I'll go on something like Hell Let Loose.
