Lost 80% player base! Update is L after L

Honestly, there are so many small, baffling decisions that add up to me not wanting to play anymore. I'm currently only playing when my girlfriend's son wants to play, just can't do it anymore on my own.

Biggest issues for me:

1. Matchmaking in the game is horrendous. Backfilling matches is an issue; I just leave now if I am backfilled into a lopsided match (which is very frequent). Matchmaking into Bot filled lobbies is a problem; so, I just leave if the lobby is full of bots, only to end up in a backfill match or another empty bot match again (meaning there are multiple partially full matches going on at once, instead of combining the players into one match).
2. Hit registration issues. One match I am a god that wins every straight fire fight, the next match, can't win a straight fire fight to save my life, even if I get the first hits. Switching servers between every match just makes it a crap shoot on whether or not I'm going to be having fun or completely frustrated with the game.
3. Explosive blast radius is just miserable on almost everything. This makes explosives really unfun to use, and they should be a blast (pun intended). Previous battlefields never felt like you had to make direct hits for explosives to work, I don't know why they changed this formula (actually I suspect it is because they increased to 3 gadgets per person, so explosives would be oversaturated; which coincidentally is an issue for Helicopter pilots because every engineer has a launcher, instead of some choosing not to carry launchers like previous games).
4. Battlepass challenges are a chore and force people to play modes they don't care about. Here's a pro-tip, if you need to force people into a mode to play it through challenges for rewards, because people naturally don't want to play it, maybe the issue is the mode and it just shouldn't exist. Also, gadgets should not have been gate kept behind challenges. And the rewards for challenges should make sense for the challenge (why is a recon skin behind a bunch of aircraft challenges? Snipers and pilots are not the same thing?).
5. Hardcore mode isn't supported. In BC2, BF3 and BF4 all I played was hardcore. Why isn't their official support for the mode by DICE? This is just dumb.

And the best part is, 1, 2 and 5 could be solved if DICE just properly implemented Official Servers, and had a server browser dedicated to Official Servers and Official-like Community Servers. You know, like BF3 and BF4 did; but for some reason they've gone all in on stupid matchmaking, and it is driving me away from the game.
