After grinding to Diamond this season...
...it hasn't felt worth it. I'm not sure why I did it other than to say I did, given that Masters last season was a gimme. Seriously I doubt I'll get to Masters in the few days left.
Predominantly, the experience has been exactly as you might expect - Rank is less a function of ability and most a function of how much time you log in and play this game, giving Respawn what it wants. What is right about the ranked scoring system is that you shouldn't be losing ranked points if you get to be top 10 in a game. What is wrong about it is, well, you can't solve the game core mechanics problems with a ranked scoring system.
Apex is never getting fixed, sure, from the point of Respawn won't fix it. Also, since they won't, because you have to do the hard work of making the game better. It's a Battle Royale, and it's on a huge map, and it's going to favor certain things. If you haven't gotten up through Platinum, aside from scads of cheaters, I can tell you there are generally still 14-15 teams left at the start of the third ring closing, often 11 left after the third ring closing. Which, if you look at the scoring system, means you potentially still end up in negative points. Nearly the whole game revolves around a bunch of teams dying during and after the 4th ring closing.
This is not to say that last part of the game isn't exciting, but it is to say look at how many minutes it takes to get to that one part of the game. Forever. Super grindy, and if you screw it up, like are one of those teams that dies early, you are hit hard and will need to make up your points over 2+ games on average, in other words, double the time.
You certainly can't just take any legend or weapon, in fact, you can't take most. You do have to switch your game play as you rank up because the things you can use effectively is narrower and narrower.
Anyway, good luck if you are the kind of person this season grinding past Diamond IV. While the scoring can get better, I really can't imagine the experience ever changing unless Respawn made some other game mode their core game mode.
