I don't know from personal experience, but I got people in my Corp running tanks all the time. Mostly cheap stuff, they almost never have them out the whole match, and if the ebb and flow of a particular match isn't conducive to vehicles, they just don't bring them out.

However, when it comes time to bring out the fine china (pricey tanks), I see the tankers in my Corp almost always running with an LLAV repping them. One battle in particular was consistently 3 and 4 vs 1 tank wise, with my squad mate being the only tank on the field for our side. I watched him dominate thanks to our buddy in the LAV repping him, and I was able to spend most of my time out in the open running beside our tank killing swarms as the 3/4 enemy tanks ran for their lives, with varying levels of success.

I would say try and find a running buddy in an LAV if you want to run tanks. As an Assault player, it would be ill advised for me to go dashing into the red blob with no support. If you want to maximize your success in a tank, you're going to want some form of support. Also, picking your spots is important. Tanks are either unstoppable juggernauts or easy WP for the reds, and this is heavily dependent on the equipment, skill, and teamwork of the opposing side.

All that said, I am on the outside looking in when it comes to vehicles. I have no SP in them at all, and if i'm in one for some reason, i'm on a turret or riding shotgun.

Personally, as a meat shield with a bullet hose, nothing makes me feel better than seeing that solid blue diamond rolling up to my position, and i'll do anything to make sure my security blanket stays alive. If you're not getting help from the little buddies on foot, you may want to start running with different people here and there. You need grunts who have a love affair with tanks, and trust me there are plenty of us out there.

Anyway, I wish you better times in the future, and vehicles will be getting some form of love in 1.5 and beyond. Hopefully it's the kind of love drivers need.
