Some ideas.
Hi. I'd like to see some soviet tank specialties such as high explosive for the js-2 and -3. I thought this would be cool when one of the main reasons why they chose just the 122mm cannon instead of a with better armor penetration, was because it had a much more powerful high explosive round. plus that the other one only where made in small numbers.
The high explosive shell should cost about 75 munitions and work well against infantry open tanks, buildings and bunkers. Big boom.!
Another thing that would be cool was if the t-34 was able to ram enemy tanks. And in this way either destroying the enemy tanks tracks or engine. if the t-34 do not hit then its veteran level fall. if the it hits it will do harm to the enemy tank and demobilize it, but the t-34 will be lost. Soviet tanks used this tactic to destroy enemy tanks, if they self had no more shots.
The t-34 specialty should not cost anything to use since it costs plenty to lose a tank. This specialty is smart if the enemy plays very offensive with large tanks as Panther, Tiger I and II or elephants. When using the specialty, the tank will have about 30 meters straight track to ram the enemy with. The route the tank drive works a little like a staffing run. So the t-34 can miss like a staffing run can.
Js-2 is all ready very strong, so I thought also that its speed should be lowered a little, since it was almost as slow as a Tiger II. The reload time should be increase a little since the 2 piece ammunition was hard to reload.
