(My thoughts and opinions are my own, you have been notified)
First off, let me say that while I dislike tanks as they are now I get their role in the battlefield and i get the way that they are used, and that they are most effective to the player who buys them. By all means they should be careful not to die in a tank because they are expensive, and that they want to get back rewards for their efforts. However, the tanks as they are right now are invincibility machines. They take no damage from small arms (as they should) but they also take very small damage from everything else even AV. They can sit on the top of an area safe and secure and rain down fire without worrying about damage as they can easily turn tail and run to safety to heal/recharge. As a player who focuses on AV primarily to combat vehicles I find it very frustrating to attempt to fight even a low level tank. Just today I had an instance where i shot my entire ammo cache of 6 swarm launcher rockets and threw 3 AV nades at a tank just to have him get in his safe zone and heal up. (Im still working on leveling up AV but it was only a Madrugar) While I don't think it should be easy to kill a tank I also don't think it should be hard enough that 24 rockets and 3 AV nades can't get the job done. I also don't think I should have gotten that close to the tank, but the driver wasn't that great and I got lucky. And I think thats what annoys me the most is that it makes it easy to get kills and hide while not being good at having a tank. Its just too easy not to die in a tank. My thought is that the tanks should be powerful anti ground forces that can be destroyed with effort just not enough that its next to impossible. If you have a differing opinion I encourage you to say what you think, just keep it nice.
