Sorry but skill issue.
Only thing true = loads of hackers.
Rest - very playable. I as all time "hardstuck Diamond" always had a field day in ranked games below Plat 4, most of time get at least 2-3 kills / 5-6 KP in pub games, in many cases even more than that.
Only thing that changed over past 20+ seasons:
1. more nubs got higher ranks diluting Plat+ lobbies with more inadequate level players than there already were
2. matchmaking system that feeds lower level players to Preds and Masters
3. hackers - total number of them
4. hackers appearing now already in high gold, for sure Plat lobbies. It still takes me just a few days or even just 1 day to go from Silver 2 to Plat 4 and then it took me 2-3 weeks to get out of Plat while soloqing in EMEA...now I can't get out of Plat because every game has hacker squad in them while I get bots 99% of a time on my team that don't even try to teamwork and ratting now is impossible as wallhacking / radar using teams just find you instantly unless in one of those 1 in 10 games where you happen to be on the other side of the map so they don't bother, they kill you in later rings where you still get negatives for ratting. And I can straight up tell when there is this 1 in now like maybe 30-50 games where there are no hackers = more often than not I either win that game or I am top 3 for sure with fighting chance for a win
That's about it.
Scoping in... players that can loot yet kill you... nah... you are probably then one of those casuals with very low skill set (that matches you input of trying to be better).
p.s. plus don't forget if you MnK - Apex since invention of cross-play has given advantage in close fights to controller players (there was even some research done regarding that which concluded something like MnK player on average getting 0.8 kills from each fight while controller 1.2 or there about) => if you take 1v1 and you lose but say enemy had left <50 health, that might be just that = your aim being not ideal / bad decision making vs controller player that is able to spray and pray and be saved by aim assist in such cases landing that extra 2-3 bullets.
If fights are lost like you do 50 and they do 200... your skill issue, that bad you can lose only to hackers.
