-snipped for brevity-
So in short, the problem is AV not being strong enough to do its job, it is not that the heavies are using a new cheap tactic, it is because the tactic thanks to unbalanced gameplay can work so effectively now.

Is it any different of a break in immersion when a scout puts an RE on an uplink and kills you instantly when you spawn? Is it any different then the spawn camping that occurs? What exactly would be your solution? Because if it is to tell heavies you can't get in LAV's well they'll just roll around in tanks or they will get into dropships. If they can't get into any vehicle that would be the shitiest suit in the entire game. So not exactly getting what you would want heavies and LAVs to be like.

When AV was more substantial I often times killed the LAV heavies were driving and killed them too through the explosion of the vehicle or least left them stranded. So explain to me and well this threat what is it that you would change or have done about the Heavy Lav situation.

Okay, then let me ask you a question, are you in favor of passanger being able to use his gun while the driver, well drives? Would you be willing to let people use side arm guns from the driver seat, if the car is basically stopped? Both of these are real world tactics and have been put into other games. Halo for the first and for the second GTA in several of the games I believe. In ways both of those real world tactics could drastically change how LAVs work, who fears them and so forth.

If you had the passanger able to use a SL tanks might be more annoyed at LAVs and target them more frequently out of the fact that an LAV could come and bite at them quickly then run away. Currently the LAV only has one real role and that is to transport people as fast as possible from point A to point B, currently that can mean a heavy just going about and mowing people down, yes an animation might help people kill the heavy easier or least predict where he will be when he gets out of the car, but it still won't solve people complaining about it.

If LAVs are targeted more and more of a threat, I believe the heavy running around just gunning people down will be dampened, it might occur sometimes but not nearly as much. This is because the LAV would become a real light attack vehicle and people would be more intrested in killing them off, since if people are having a passanger gunner that means another 50 points per LAV killed. The reason why LAVs aren't hunted down more by dropships or tanks is because they are not seen as a threat to them at all. The most they are considered usually is an annoyance to infantry, via the heavy ganking people or the jihad jeep, which doesn't always work out so well.
