Ideas for improved vehicle gameplay

Aside from the obvious glitches (devs: please fix) related to faulty hit registration, phasing out of the map, game crashing, and framerate drops, I want to raise attention to several general improvements that could improve Battlefield 6. I encourage discussion and feedback, and simply ask that everyone be respectful. 

Game Modes

1. Add casual versions to Rush and Escalation. Not strictly vehicle related, but Casual Breakthrough is phenomenal mode and reminds me a lot of Capital Supremacy from EA Battlefront 2. I'd love to see this experience brought to other game modes so as to lend greater variety to casual/beginner players (or veteran players looking for a more low-octane gaming session). 
2. Improve bot skill level in Casual Breakthrough and require at least 16 total players. This is still way less than the standard 48 or so in regular Breakthrough, and would keep gameplay more lively and competitive (while still keeping it more relaxed than the standard mode). 

Game Balancing

1. Improve the broken splash damage on MBT primary weapons. I've posted about this before, but the issue got even worse after the winter update. I'll fire a HEMP round directly at somebody's feet, it'll hit the ground right in front of them, and it'll only deal 33 damage. What the actual ****. Firing dozens of times to only receive 10-20 kills is broken-levels of underpowered and outright prevents proper competitive gameplay for armor players. 
   1. They're virtually useless. There's so many ways to kill them and so many rockets in your average game, but it's almost impossible for them to kill anything - let alone try to push objectives or present a threat to the enemy team. 
   2. I won't even ask to alter the damage tables or RPG over-saturation in games. Just please make the tank's gun usable. Let's start there. 
2. Lower sniper rifle damage from 100 to 99. It's far too easy for snipers to dominate matches and the skill level required for sniping in BF6 is just too low, especially considering the significantly smaller map sizes relative to previous titles. It should be harder to snipe. Not unfairly difficult, but enough that it requires significant skill. If the damage is lowered to 99, it'll still absolutely allow one-hit headshots. 
3. Increase Javelin (Glaive) damage from 300 to 400. Especially for having such a long lock-on time and less rockets than the RPG and M136, and tanks often having 1-3 engineers repairing them, the Javelin is pretty useless. Please give this weapon something to show for itself, some kind of basic value. 
4. Decrease C4 damage versus MBTs and IFVs. I know I'm probably going to get mad hate for saying this, but running up to a tank, throwing C4 on it, and destroying it instantly is just stupid. It's goofy, ridiculous, and unrealistic. 
   1. How does it make any sense at all for a dedicated anti-armor class to be unable to defeat a tank individually (typically, given repairing engineers as a common occurrence) but a sniper can just run up and kill one on their way to an objective? If you want to make tanks that easy to kill, it really becomes a question of why you want tanks in your game at all. They're supposed to be hard to kill. They're supposed to require skill, effort, and collaboration to defeat.
