As a very experienced tank player in almost every battlefield starting all the way back to BFBC2 this was the biggest issue for me thus far. I have started getting used to swapping from first and third, but doing this constantly can cause me to lose my bearing. The health of the tank I think is fine, but the rotation speed in first person I feel should be something closer to bf2042 or bf3/4.
Engineers rockets I think need to get some form of nerf. Either decrease the rockets, slower reloading, or decrease the damage done. A tank should feel powerful and should get easily punished by making bad decisions, but when operated smart by using infantry as your frontline support it should not be able to be taken out by 1-2 engineers focusing you for less than 5 seconds when tank v tank fights last longer closer to 10-15 seconds.
First fix for tanks should be the first person rotational speed. On mouse it took me sliding across my desk up to 7 times just ti turn 90 degrees which is ridiculous.
