The kt not being viable is because of the 60 range td buff alongside kt nerfs.
No. The KT is not viable because you spend an obscene amount of total resources to buy a mobile bunker with absolute trash mobiliy at vet 0 which gets roflstomped by either the zoom zoom F1 car that is the M36 Jackson or gets sniped by the recon mode T70 and SU85s combo. Brits are probably the only faction where the KT is a safe choice. Not even gonna go over ram bullshit which is how I always lose the KT vs Soviets.
If the KT had a bit more mobility it would be in a much better spot right now.
