I actually prefer vehicles to be weak, but I think their price needs to reflect that weakness. Right now they are overpriced. There should be a big 35% cost reduction on all vehicles to make them reasonably priced. Cheap but crappy vehicles are far less annoying than strong expensive vehicles.

I think dropships need to be fast, but swarm launchers need to get progressively faster at higher tiers (or there should be a skill to increase swarm speed) so that swarm launchers can be useful without making all swarm launchers too strong without.
Dropships should have the option to remove turrets for extra CPU/PG to fit more shields or armor. This would allow them to be more durable and reliable transport vehicles.

tanks are pretty squishy considering they are tanks it should take a minimum of 2 guys to take out a tank increase the HP by 30% but separate the main gun from the pilot and make their guns require ammo and a special equipment slot for resupplying tanks.

Dropshits for a transport their extremely fast conversely for a transport their pretty squishy think dropships as a whole would benefit from having that reversed more tank but less speed.

LAV pretty satisfied with these just add a module that puts a protective cover around the gunner.

swarms need fast radius with less of this insane turning speed, they should be quick not agile, also fix their stupid flight path just have the missile fly straight out from the launcher until it has LOS then it archs towards the target and speeds off.

vehicles need to be team vehicles and used by the team not by one guy for use in random matchs to rack up kills they should be away for corps to exert power by fielding them since only corps would have the required cooperation to use them.

most gunners shoot at hills because they have infinte ammo also just get them on the comms and tell them to stop. if they dont have comms then why are you playing with them.

swarms should do less damage so their not so OP in terms of damage agianst things like tanks but should have a change in mechanic so they hit Dropships

I don't want infantry only at all, what is up with people alway referring others to CoD? I just don't want people to become unstoppable killing machines just because they can afford to spend a few hundred thousand ISK per battle.
The advanced and prototype vehicles are pretty beefy, so if you want expensive powerful tanks, then use those. Militia and standard tanks however don't need to be strong.
