Just to be fair: He has a point. Compare 5th tank to 7th tank in upper row. Both get hit from the front. Thats a huge difference already. Reason: low penetration vs high front armor = RNG
You can compare second to third tank in upper row too. Not such a big difference, but RNG still leads to situation where the Elephant will get destroyed with some other hits or can escape depending on RNG of rocket strafe despite some other hits.
My main issue with the pentration nerf is that the penetration nerf leads to the situation where you want to attack from the rear always. This will lead to a longer approach time in many situations and will make the attack more predictable (you know the direction it is coming from). Especially at the big 3vs3/4vs4 maps. A faster tank like a Panther or PZIV may escape completetly in this higher time window. So this is a bigger nerf to the big game modes than the small ones. Don't like that, because Soviets struggle there while doing absolutely fine in 1vs1. We don't need any futher nerfs to 3v3/4vs4 allied performance, its bad enough already.
So then don't use the rockets from the front if you don't want to deal with RNG. Also, it still does a ton of damage considering that it's just ONE!! call in ability. If you have teammates nearby (or evwn your own tank destroyers) you're going to have a much easier time blasting the superheavy to death. Add to that the stun you're assumedly putting on the tank before the rockets even come in (meaning allied TDs get a chance to hit it for free) and it's really not that big of an issue. Killing Axis superheavies should be somewhat of a team effort considering how much resources go into them.
So you can't solo the Elefant any more. It still does a lot of damage. I play nearly exclusively 4v4s Allied and I think this change is warranted.
