How do you guys have fun in MP?

I've tried to adapt in every way, even changed my slide and jump buttons to always perform these movements (L3/R3). I'm playing exactly like everyone else—sliding every second, jumping, sliding—my performance has improved, I always stay between 1 and 2 KD, but I just can't enjoy it. I feel exhausted from having to play this way. I need help because I'm level 61 in the Battle Pass and don’t want to lose the COD Points I spent.
