STOP USING JS-2 TO KILL TANKS? STOP USING A MOST EXPENSIVE HEAVY TANK TO KILL TANKS?
Arguing a most expensive heavy-tank SHOULD loss to another cheaper heavy tank, or even a tank which cost half of its fuel is pointless.
AI ability in a late game warfare compensates little how it does in terms of AT role!
STOP USING "IT CAN KILL INFANTRY IT'S FINE" ON A MOST EXPENSIVE HEAVY TANK IN GAME
This is a poor argument. A unit's cost-effectiveness is based on both it's AI and AT abilities.
For example: a brumbar is about as expensive as a Panther, but is only good against infantry. The IS-2 is basically a Brumbar and a Panther combined with higher armor and much higher cost.
I don't have an opinion on whether the new IS-2 is cost-effective or not yet, but that was not a convincing argument.
