I see you've decided not to take the whole "reading and understanding" part of my message to heart. Let me give you a hand...
I'm actually doing quite well in the arena, or at least I would consider S4/G1 to be quite well for being 3 months in and not spending money except one instance of the daily gems at the start. Maybe you don't, I don't really care, I'm perfectly fine with it. None of my objections to the arena have been that I feel I should be doing better. If anything, I've said I'm perfectly fine with if I did worse, and perhaps I should be doing worse. Had you actually read anything that I've said instead of constructing your straw men, you'd know that.
Second, if anything, I'm arguing against my best short-term interest. If Plarium did what I'm asking them to do, I would most likely be doing much worse in the arena than I am right now. Part of the reason I'm doing well is because I'm exploiting the nonsense matchmaking system, the very same that I'm saying should be changed, and in such a way that I wouldn't be able to exploit it. This should be in Plariums interest as well, assuming of course that their state goal for the arena isn't an outright lie (which it probably is, but that's another matter). Had you actually understood anything that I've said, you'd know that too. Then again, perhaps the concept of wanting something to be improved even if it's not to your direct benefit is completely alien to you.
Third, I'm saying that the arena as it is, is not sustainable. There's no competitive environment to be had when time is such a fundamentally important resource. Short of a time machine, there's no way anyone can just make up for several years worth of advantage. Money is a replacement somewhat, but even that won't be enough eventually. I don't know how bad it is right now, but I do know it will only get worse. Player growth required for the arena to function as they envision it isn't possible, even if player retention isn't as abysmal as it seems at a glance. There will come a point when all your can-do and peppy attitude won't make a damn bit of difference, because regardless of what you think, you can't will yourself to resources that you don't have, and player skill is such a minor factor that it's not even worth considering. Had you actually understood any of that, well, you would at least have been able to present some sort of argument instead of preaching from the git gud gospel, with apparently no concept of what that actually means in a game that isn't skill-based and how increasingly difficult it becomes.
