Couple things:
1. The Tiger I had 120mm in the mantlet, the front hull/superstructure were 100mm.
2. FH gun values are based at 1000m penetration, at least going from the numbers in the code
3. The Churchill 6 has less HP then the Tiger
4. The Tiger has PzG40, along with every other Axis tank (some situations downright wrong), and is 1 shottable to the front with the Panther or Tiger.
5. Some Africa maps actually have the Axis tanks dominating, the large breakout from Tobruk where you have IVF2s and III-Js against Crusader Is and Grant is one of them. So they would definitely need to be addressed map by map, and not just by nerfing some vehicles.
I vote the maps are generally the problem when it comes to balance. Balance is not swayed in any one direction, it all comes down to loadout vs loadout and terrain. We've had over 6 WaW battles since 2.26 came out, all generally fine when the loadouts match up equally. In our pre-campaign scrims, we actually had maps that both sides would switch loadouts, and maps went both ways over the 11 hours.
And Para, as I said, if you really want to remove the Sherman's HVAP, then you lose the PzG in the Stug, PIVF2/H, Panther, Tiger and King Tiger, because none of them had it on the western front. It that's the way things go then so be it, just realize that door swings both ways (and actually hurts the PIV/Stug and Tigers offensive ability if going by the current build)
