People always tend to go for KT because, well, it's just there. A stock god-tank always available in the end game. A generalist heavy tank that's good in almost every situation. Not OP to the point where it's a one tank army, but still good enough to be worth it's expensive cost.
CoH2 is a good enough game as it is with its current RNG, but if relic wishes for more people to take it seriously as an esport, then it would need pseudo RNG to even these RNG spikes out. A more consistent RNG would definitely help a lot.
I'm just gonna say this quick since my last post (which was reveling at the stupidity of the first two posts) was removed, I'm gonna say something on-topic:
The T-70 is a little shit-eating wipe machine that kills everything walking with two feet.
However, once your opponent gets a real tank, consider that cute little midget obsolete. It will then serve as nothing more as a recon tool and maybe a harassment tool in one of the off-points (even then if it stays too long, it'll most likely get killed by the tank responding to the T70 threat).
Whereas the other light tanks have their uses late game, like the stuart's very useful abilities, and luch's survivability + good veterancy, the t70 is just too flimsy to survive more than (TWO!) shots from most anti tank.
the only thing that needs some changes is the valentine. that thing is pure ****.
OKW doesn't have any early game mgs, so a good way of countering sturms are to attack in force, while your capping units cap. When you first see the sturms always focus them down first. Oh, and buildings work good against them, because if you're in a building the green cover won't be nullified even if the sturms close in point blank (and you won't get pushed out).
