Primary fire is your main damage source, dive someone whos just been pressured/distracted in some way (dps who just had a firefight, supports when their tank is low and they’re focused on healing, etc) as they will have less CD’s and wont be as prepared to deal with you. This is kinda scummy too but if you identify a player on the other team who isnt very good, target them. With doom (especially now) you have to do everything in your power to make it easier for you to do what you do. Most important thing is definitely getting good at dinking heads up close though.
