Why It Is So Weakened Kt

ARGO: To be honest with you It's not all about actual historical stats, I personally do not see any real problems with the KT although I myself have yet to own one but I will say that a few buddies of mine have them and I do one on one duels in the training room and I have yet to be able to best him in my IS4. KT fully upgraded is a very powerful tank my friend. Now to also put it another way is that my IS4 does better for me than my IS7 and you would think it would be the other way around but my theory is that aside from the stats or crew ratings or kits and modules it also comes down to what works best for your individual playing style.
Besides, if they made this game 100% historicaly and statistically correct it would be a rather boring simulator.
