Physics and Battle Tactics

If no, WG should put a system, like other games, to put a 10-30 seconds cooldown on a tank in these situations.
Explanation:
If I hit a tank and kill him, I get the kill credit (like it is now)
If I hit a tank and not kill him, but instead, he decides to kill himself (jump off a cliff/bridge or get in water) thinking himself like a BAWZ and does not want to give me a kill credit. Instead of this, if he dies in the next 10-30 seconds after I touch him, I should be able to get the kill credits if he dies by ''natural'' death. But if this happens after 10-30 seconds, I should not get the kill credit because his death was not ''cauzed'' by me.
Same thing may apply, but I am not really sure, to another situation:
Let's say that you hit a light tank and because of this he was forced to jump in the water and die, do you or should you have the kill credit?
If you push a tank int he water and he dies, it is considered like a kill on ennemies or a team damage on allies or should it be?
