Actually, I liked the JgdTiger as it is. I´m ok with the camouflage, as I learned to deal with it. The thing which pisses me of the most is the spotting system.
I´m ok with having tanks hidden in bushes, but as soon as they shot right infront of you towards you, you should be able to see them. My biggest advice is still to screw all this (in my eyes) bugged and unnecessary spottingsystem and go for manuel spotting. This will make players more happy, as they can clearly say, that it was their fault that they didn´t saw the tank which killed them, then having some not understandable maths behind it.
