I would like to make a quick suggestion along the lines of this thread:
As it is right now, people crewing tanks should perhaps be a bit more fearful of death... I mean if you die in a tank, the longest wait you would have to hop back in the action (with a brand-spanking-new tank) is 20 seconds. Perhaps the respawn time for tanks and tankers ought to be tweaked up, so they don't respawn with the regular forces' timer.
For example, you and your tank are destroyed. What if you had to wait 30 seconds no matter what before you and your tank respawned? This would solve a couple problems. First, you would have more of a reason to avoid death while in a tank, as you would have to wait longer than regular infantry to spawn with your vehicle. Also, if you AND your tank spawned at the same time, you wouldn't have to worry about losing your ride if it spawns before you and some loner makes off with it.
I mean, in Arad, when trying to capture the enemy's village point, you can kill an enemy tank and literally have to deal with him again 10 seconds later!
Granted, it doesn't happen every time, but with the current spawn system for tankers, it happens often enough.
