Oh I can definitely relate to almost everything you brought up. I am quite "new" as I played at game release but not for long, and just recently got addicted to it right before the end of season 7. In a weird way, I like the re-balancing but only when it changes overused weapons and not introducing super OP ones.
I played a decent amount of duos but I'm not sure what bug you are referring to.
I can agree with the players too, I've wiped a whole team solo in 3's, and other times it feels like I'm against pros. Apex is definitely not the beginner FPS game, the team coordination and advanced movement is hard to overcome, and the necessity for friends to play or risk losing 24/7 being solo is quite annoying.
Great comment, Thank you for your insight!
