At the time, T34 was also even cheaper then it is now, below 300mp and at 80 fuel.
Its already too expensive to use it against mediums in situations other then certain loss.
Why do you want to nerf already extremely underused and niche ability, because it has too good synergy with off-map that instead could lose potency and cost instead is beyond my comprehension.
Using it already costs you a tank, unless you're in really favorable position to recover it and you rarely are if you need to use it, paying additional cost to lose a tank doesn't seem like a sane solution at all to me and your solution makes ram even worse of a choice in situation where you don't have that one or two doctrines with offmaps to support it.
Therefore, as I have said, the ram should NOT disable T34 if it was to cost anything or, if it penetrates, it should disable opposing tank the same way it disables T34.
If offmap is too strong with it, again, reduce potency and cost of the offmap in question, don't break the ability for ALL of situations just because of one.
I understand your point, but presenting it as the only way to go does not make sense.
Both abilities (IL-2 and ram) by themselves are pretty much fine. But nerfing the synergy in this context is very hard, so if the community/balance team agrees that this issue is too big to just let it go, then one of the abilities must be changed.
You say don't change ram because it would affect the ability outside of the combo. That is perfectly true. But please explain how doing it the other way around does not affect the bomb/strafe run outside of the ram combo? The IL-2 bombs are also used on static emplacements and buildings, the strafe can be used against all other tanks as well. Nerfing them would cause other issues.
Your suggestion is not better, it is just different, so you should present it that way. Ram is an ability the T34 can basically live without. If it's too expensive vs some units, then don't use it against them, simple as that. The T34 has other issues than underperforming ram. That's why I say change ram, not the offmaps. Because the effect on the rest of the gameplay is lower.
Yes, my suggestions are a straight nerf to ram. That's why I also proposed a buff to the secure mode to at least keep the T34's utility in a normal state.
