I loved the vehicle play, particularly the new turret traverse system, however the biggest drawback is the resupply depot system.
While I would love some variant of this system, the current one creates a lot of problems. The meta is essentially to camp these points, which becomes repetitive and artificial, and discourages PTFO. I think we should be able to resupply on cap in addition, such as the case in War Thunder (and only on an objective you hold).
Far too often would friendlies inadvertently, or even purposefully, blow up our own supply depots, particularly to troll friendly tankers, if they didn't get the spawn, or if you're alive too long, etc. I think this system will become even more exploitable with time, by both friendlies and enemies alike.
Furthermore often enemies, or friendlies, would just destroy every single depot on the map religiously, and this just ruins the entire vehicle experience for both sides.
Furthermore, I had my tank stolen perhaps 5+ times while rebuilding supply depots, both by friendlies and enemies. I wanted this to work, but in the end I didn't even bother, I just rolled all the way back to our spawn. It takes the tanker just far too long to build the depot, and we have no smoke grenades, so that makes it all the harder.
I'm not necessarily saying remove the resupply depot system, but I'm saying it really makes the vehicles far less enjoyable in the current form it's in.
