@EdwardDLuffy happy to help!
Personally, I don't really like double tap, especially when I am dealing with moving targets or shooting people at longer ranges. If I miss then it just doubles the miss and I do miss a lot
...besides, I can just as easily spam the trigger button to shoot lots of bullets in a short amount of time. However, if you're getting better results with it then that's great! It's important that you have a loadout that you can feel really confident with.
As for the prowler, are you using it close up or at a distance? Burst prowler is like a shotgun, you'll want to hipfire with it almost within punching range, because it becomes much less effective when you're further away. I would generally also recommend using the highest FOV setting, so it's easier to track people when you get that close. If they have a low FOV then it's almost like they have binoculars on and they can lose track of you more easily if you keep moving outside of their limited field of view. That's a big advantage, because it makes it possible to shoot them without taking too much damage in return.
I'm glad that you had fun, but can you think of a way that you could've won the match? It's good to take a moment after each match to think what you could've done differently with the information that you had to achieve better results.
One thing I wish my teammates would consider more before pushing or running is some basic math: if everyone has 200 health and one guy pushes into a 1v3 situation then he'll need to do 600 damage total to the whole squad, while the enemy would only need to do 67 damage each on one single target. That math is disproportionately skewed in favor of the trio, so you shouldn't push that unless you're an Apex god. Something similar applies to a 2v3 fight, although your odds are better there. When the odds are heavily against you then you need to find a way to even those odds. Maybe look for a care package, so you can grab an OP gun like a Kraber or a Devotion and if the last two teams are fighting then that's your only chance to push and get some free shots in (ideally a knock against one or more enemies), before they turn to fight you. That's also when someone like Crypto becomes surprisingly useful, because he can EMP the last 2 squads (even indoors) while they're already hurt and then finishing them off with a few nades and a powerful gun will be much easier. The drone is also a good tool to get the last two teams to start fighting... if you EMP one team and then keep harassing them with the drone, so they'd make a lot of noise trying to shoot it then that can entice even a solo player to rush in towards the action to hit the distracted and damaged opponents.
Anyway, there's usually always something more that you could've done and if you figure out a winning strategy then you can use it next time when you're in a similar situation.
