Changing argument from fun and casual play to matchmaking and ranked... :)
Adding touch of personal / emotional insults... ok.
Totally wrong about matchmaking - there are even official topics about it being changed because Imperiahal and other influencers of the game were too tired to queue for too long and demanded ... wait for it ... exactly the same as you = fun and casual games, so now they are casually added to plat lobbies and stomp them. And it is NOTHING to do with player count.
How do I know it -> if you take even EU Apex legends FLG there are constantly at least 50-100 diamond+ players on in peak time and like half of that in off times. So that's already a server or two. Battlecord discord -> add few tens more + higher ranked (cheaters mostly there for sure) and you have servers! where plats are not needed.
So educate yourself ;) or just be quite :)
What I defend is that assuming from what was written we both have invested 1000+h into the game which is let's call it equal amount.
Yet you can't get out of gold or so you say and have no fun.
I got out of Plat 3 to D4 previous split in 3 days, split before that with duostack in 2 days. With duo / tristack reached D2 even with all **bleep** hackers and Preds in my lobbies, have a video proof how we won 2!!! Pred lobbies in a row. Yes it was **bleep** lucky but we still did it and with 5+ KP including in one game aping successfully looting Pred 3stack.
Long story short - you are demading Apex to be what it NEVER was. Maybe back in the days competition was lower...yeah I would say so. Cheating was not so spread - 100%, now you even see some gifted empty head ppl cheat in gold, plat is littered with cheaters and Diamond4+ was always about cheating just how much = be it RC filters or radars or aimbots with wallhacks.
Comparison to what you are demanding is to get into boxing ring with superheavyweight and ask him not to hit you too hard... forgetting that even his not too hard will knock your brains out :)
Adjust or just leave the game, don't make Mario Karts out of Apex Legends :)
p.s. you don't need to be "9 to 5" in Apex to be good. I came to play it after 7 years of not playing basically any games and instantly went to P3 and season later to D4 (soloq) and ever since I have been only D4+ almost reaching Masters once (season 12) and multiple times being in D3-D1 depending on how much I try / if I have duo/trio.
