i know that Tanker do not use a lot freeze turret a lot for simple reason that they prefer firebird for it cause it's after burn effect! that after burn effect is making the diffrence and kind of real so tankionline tryed to balance the situation but no success but here is what i propose when you are frozen your tank loses efficiency not only speed even your rurret is slown but the natural effect that you need to add is if you try to move while you freeze you damage your tank cause that make a sense metal became like glass when frozen and if you do not move at all no freezing moving damage is caused, and you have to wait until you becam to move with no freezing damage
