Ram + IL2 precision bombing only works on Ele or JT, maybe on snared/stunned KT if executed super well. It is too slow against medium tanks. So no, ramming + IL2 precision bombing doesn't work the same way and on top of that it's also twice as expensive as the IL2 AT strafe.
it is dedicated anti tank. what is so difficult to understand about this? that means no damage whatso ever to anything else . neither infantry or buildings.
yes il2 precision is expensive because you can
1 destroy an enemy garriosn with it
2 destroy a limping tank with good anticipation
3. clear out enemy arty pieces
4. clear out pak 43
5 area denial.
it is a multi purpose ability while il2 rocket strafe is just a situational ability and depends on rng. i have seen it hit houses and trees in the path multiple times. im not discussing anymore on this now. you can keep on if you like
