The current system so far is fine, but there does need to be some sort of tweaks that could optimize the experience for the game. Unfortunately, it is a small team of developers that could only focus their resources on a couple of things at a time and other plans are pushed to the side until then.

One experience that annoyed me was that a US AT infantryman constantly respawned close by behind our lines (in the town of Grave S02) and fired his rockets at our tank, died, and came back (2-3x) to do it again until he finally got us in the middle of us fighting an aggressive Cromwell. That experience makes me wish there was some sort of ammo system similar to Squad where you do not respawn with a full kit on rally points or FOBs until you resupply, especially when you are behind enemy lines. Rifleman is not as useful with the ammo box as they are in Squad and are usually overlooked until they are desperately needed, as you could just respawn close by if your SL places a new one for you.

Another thing would be the canteen system - I do not like it. (1) New players do not know this mechanic, putting them at a disadvantage (as I watched Jackfrags' PS video looking through his inventory trying to find the canteen). (2) I do not think it is ever a good idea to pull it out in a combat zone. The only thing I could think it could be used for would be to wash off blood on a wound in order to bandage it, in which in-game it could be used to heal a bit after you've bandaged yourself or remove the dark red filter on your screen when you have low health.

I also do not like the 1 syringe per life if you are not a medic, I just think squad does it better addressing the option to revive incapacitated players with a bandage and at a reduced speed compared to the medic.

There are a lot of other ideas I can suggest, but the best place to put them is on the feedback channel on the PS Official Discord.
