Oh stop it, you're making me blush. <3
I'm pretty stubborn in regards to my style of play. Even if the situation blatantly calls for a more campy, conservative style, I like to try and run around as much as possible. If I slowed down my game a little bit more I could pull even better scores, but I don't have fun doing that so that's a no go.
The best tip I can give pertaining to a more fast-paced style of play: situational awareness is everything.
When I'm warmed up or "in the zone" my aim may be on point, but you'd immediately recognize that my success comes from noticing things other people don't. Some of these things I'm talking about are skulls from teammates, teammates and their positions, silenced enemy weapons, spawns, who wins/loses gunfights, etc. I could babble on about it forever, but yeah, you get the just of it.
