@l_Darkjedi_lA large chunk of what you mention is issues at launch and does not apply anymore, nevermind things that were never true even at launch.
Class-based and hero shooter are not mutually exclusive. 2042's gadget balance issues (which existed mainly at launch, and have not been a thing for a long time) were not due to it being a hero shooter. Overwatch is THE "hero shooter", even though I'll still consider it a worse version of TF2. It has 3 classes of heroes, with extremely specific roles. Somewhat like what 2042 has now. Rather, no one cares about these waaaaacky personalities, especially when they start mouthing off cringe at the end of the round (which is not a thing anymore), and that they're a transparent vessel for more monetization. If you want to talk about the confused identity, this is it - matches open with "we're all gonna starve" and horror-esque music and used to end with "I'm just better than everyone else".
2042 did not show you how much damage you dealt to vehicles and what parts you disabled. With it being difficult to judge exact numbers off a bar mid-combat that is only sometimes visible, people assumed there was no directional damage. There has been directional damage since launch. The damage you deal is shown now (though floating point and particularly <1.0 damage is broken). Specific part disabling however is still not communicated. AFAIK only part damage has been somewhat simplified in what triggers it (I'm still not exactly sure on what does trigger it outside of EMPs or hacking).
Hitreg was bad at launch. Hitreg is fine-ish now. Dusting happens, dusting happened before in previous BF games as well. The hitreg was nowhere near as bad as BF4 at launch.
The reddit post you reference is meaningless. Read the DICE reply about it. https://www.reddit.com/r/battlefield2042/comments/r8a744/comment/hn833jf/
There WERE mouse issues back then. This reddit post does not demonstrate that. Things have been improved now.
Your "gameplay issues" are mostly nonsensical. Pretty much only the helicopter one is valid. Tank drivers don't need to know where their gunner is aiming, it's irrelevant; at launch, gunner shots would veer off whenever the vehicle moves (probably inheriting vehicle momentum more than they should), this has been fixed. Is this what you're referring to?
There is only one AA vehicle, the wildcat. It has no 20mm flak. The 20mm flak on jeeps was added most likely with the sole purpose of being a counter to nightbirds a while ago. It is pretty much ineffective against attack helicopters, which are the current flavor of overpowered helicopter, or transports. It was not intended to be your team's main AA option, hence why its range was nerfed to only 200m. It's still good to take out overly aggressive nightbirds.
If we are talking about launch, back then the 20mm flak did not exist, 60mm flak pods could farm infantry with massive splash through walls and the wildcat had the 57mm which was pretty damn overpowered and could wreck any air and ground vehicles. Right now, I'd say the 30mm is underpowered only because attack helicopters are overpowered and have too much health given their mobility. They used to be incredibly slow and have low health, DICE decided to buff both of these aspects at once.
The "some other AA" in BF4 was the Igla, a launcher that required you to hold the lock, NOT fire and forget like 2042's FXM, and for that rewarded you with a faster rocket and longer range than the fire and forget Stinger, which had the same lockon distance like in 2042, 400m.
Back at launch, having only the M5 was pretty bad, however playing the overpowered combo of it and Angel being able to fully resupply yourself and give yourself armor kinda made up for it. Now, you get a launcher that deals 35 damage to tanks to the turret and side, and 44 to the rear, and a good amount of ammo. No shallow angle mechanic, always 35. This is WAY stronger than what was ever in BF4, and that's not even factoring in AP UGLs or the AT grenades or whatever else which also was not in BF4.
Ziplines were already a thing in Battlefield, they were in Hardline long before Titanfall would get desecrated and you could even create one wherever you pleased rather than having them only in preset spots.
This reminds me, I wish people would stop conveniently forgetting how bad BF4's launch was just because BF4 is good now. What happened to everyone posting threads on Battlelog saying they'd never preorder a Battlefield game ever again? People forgot that, and after they were officially told by EA to not buy Battlefield games? (Not quite exactly but close enough)
There are tons of things to complain about with 2042, in the past, less so in the present, but a good chunk of your reasons are untrue, nonsensical or misrepresent things. If you want another legitimate reason - 2042 would cause Xboxes to instantly shut down. AFAIK this only happened to very few people, but I think that's pretty pretty bad.
If we accept mediocre games, then mediocre games are all we'll ever get.
