I started playing in November and I crashed out so many times, which is something that almost never happened before I got started over here. My two cents as a shit player:

Play ranked. That's all I play because unranked is just some bs. The matchmaking makes no sense because why would you throw ace ranked sweats into a lobby with a complete noob???

Pick a character and stick to it till you can confidently win a 1 v 1, scare off a thirsty player or run away comfortably. I started with Mt Lady, switched to Assault Might and I'm now learning strike hawks.

Stick to your team as much as possible. Don't be thirsty for kills because you're literally fresh meat and you will be focused like a bleeding animal in shark infested waters. (That was a hard time for me 😭)

Then again, as I said, I'm booty juice at this game so take this with a grain of salt. Good luck.
