I choose to persist when I see a team with unpromising-looking banners. It's just a mentality thing. About what the game means to me.
I've played my Team Fortresses, Counter-Strikes, my Unreal Tournaments, my Overwatch. Decades of my life playing shooters competitively on PC and console. I have no idea how many figures of matches I've carried across all of those games. It has been a long time since I have felt the need to prove myself. I just tryhard and if my team isn't quite on the same level that is more than fine. Even the worst player can help the squad in a baiting role.
If I wanted something truly competitive I would rather go back to any of those above franchises that I mentioned. Apex is a FUN game. I would even go as far as saying that good teammates can make a game boring from time to time.
Apex Legends is not very appropriate as a true esport (or any BR for that matter). Tournaments exist for these games because they have a large viewership. Too many random variables to be a proving ground. And you can never use your teammates as a measurement of your own skill.
I would rather be the guy that carries than the guy who gets bored of winning. The only thing I don't like are AFKers. I'm working 6 days out of 7 and I don't have patience for XP farmers who stay out of sight for the whole match. Or those that join the queue and walk away like they didn't just join a queue. Wasters.
