Battlefield 6 balance suggestions

Increase pistol damage by 20%. I wanted to use my pistol more but wasn't really incentive to use it, pistols do virtually no damage

Agreed. Its really hard to get pistol kills unless you catch someone completely off guard. I will say that I do appreciate them being more of a back up after the G17 being broken for the lifetime of BF4

Whenever someone is in a downed State they should be able to pull out their pistol whenever you have a buddy dragging you and reviving you there completely defenseless 

I dont think this is really necessary. BF has already evolved to letting anyone revive, not just medic. Now they've added the ability to drag and rev at the same time. I don't feel like this mechanic needs to be buffed at all anymore.

Reduce the sniper glint don't take it out completely just reduce the brightness and if it's possible  remove the sniper Glen all together if a sniper is in a shadowed area or inside a building 

Sniper glint does seem excessive, but I understand the need because of how detailed the maps are these days. That said I think a good compromise would be significantly lowering the glint and then maybe make it more noticeable when they hold their breathe or something like that. Would allow you  to be more stealthy until you actually go to take shots.

increase the damage output for the m39 3 chest shots to kill and three headshots to take someone down is ridiculous 

DMR balance is always hard to find a good balance it seems. The second DMR sniper almost seemed completely OP because it was always a 2 shot no matter the distance. That said, 3 shots seems like it can be a lot especially having to follow targets. I think they really need to make the 3 shot DMRs effective at closer range maybe with a better headshot multiplier and hip fire, but still have heavier hitting DMRs that can 2 shot with downsides of mag size, poor hipfire etc.

Reduce the time to kill with weapons dumping an entire magazine into a single Target or 2 doesn't make sense 

I feel like this game suffers from the effect that it feels like you have to mag dump enemies, but you take 2-3 hits and die. Could be net code or something, not entirely sure. Its not game breaking but it doesnt feel like I can tank the same amount of shots that I put into enemies at times. That said, I feel like the damage drop off for some guns that be a little much. Some of the ARs do like 12 damage at range which feels pretty insignificant. I think SMGs and pistols should suffer heavily from this, but other guns maybe not.

Pretty please bring back hardcore servers and modes (I love battlefield 4 and I that's all that I played was hardcore and on BF 42 I played hardcore)

Im sure the final release will have hardcore options, but almost definitely within Portal. The point of the beta is to do a mass stress test for the game. Im sure they didnt plan on releasing every mode during the beta so they can filter all the players into testing out the most common modes first along with non-hardcore gunplay and balance.

Slightly increase the revive speed for non-medic classes (probably by 5 or 10%)

My first comment also applies here.
