My advice, It's amazing how easy it is when you're shooting someone/s who are not aware of your position, usually behind them. This is what wins games, be unseen, be that guy behind your enemy. Grenades first and then mop up and move on quickly back to your team for safety. Momentum. If you get first super especially in survival just use it for some relatively uncontested kills to put you in an advantage for that round. Heavy. Stop the other team from getting it. Even if getting it doesn't result in kills for you, stopping your opponents from getting it will give you a much better chance of not flat out losing the round. Decide early where you're going. You're going to get pinched hard if you flounder. If you're going to all move together closely do it quickly and rotate fast because you're likely to catch their flankers if they went for that strat and you can fight them 4v2 before their buddies show up. But they're probably off grabbing power so be careful. Don't peek. If it looks like they're all hardscoping a lane with graviton lance don't expect to live long enough to step back in to cover after pulling your trigger once! Graviton lance will average about 70 a pull... so x3 or for guys laning you will be 200+ damage instantly. You're also likely to now turn into exploding void balls that kill or severely weaken your but hugging team mates next to you. Which leads into the next point. Know when to be patient. Facing down a lane knowing your enemy is doing the same is a regular occurrence. But do you know if there's only 1 guy waiting to peek shoot you or 2.. or more? Who is with you? Do you have instant kill potential on an enemy if they peek? Patience is key here. Don't rush to take that shot down range when you could be outgunned already. These are some tips to think about, I'm not claiming to be good at comp either! I struggle and probably won't get fabled rank so whatever but hopefully someone finds something useful here.
