"Super Heavy tanks" where not broken to being with, they become broken when they tried to "fix" them.
And this is quite a common pattern on the Coh 2 patches history, units become OP and then UP again and persisting problems being fixed at a very low rate.
Heavies were broken in a sense that they were never used beside sometimes the Pershing and the Elefant in large team games. OKW was designed around the KT and also OST is supposed to regularly bring on a Tiger. The game is designed with heavies in mind, and to be honest it would be a shame if the game did not include them properly. But that is very subjective.
Balance team decided to bring them back to the game again which was a very good thing. So they did a complete rework of how heavies function. Turns out that you can't foresee all consequences of a complex set of changes. No surprise here.
It is a bit of a shame that it took multiple months until they might finally be fixed, but as a matter of fact the meta now is not really worse than the meta we had before gameplay wise. And demanding regular updates and fixes from people that spent their free time on it would be inappropriate, especially since they have done an exceptional job in the last two years. CoH2 has never been better and strategies more diverse, even if there are issues and current metas. Earlier every faction had three commanders at best that were somewhat viable. There was no selection. Now you at least have to pick a few from a group of viable ones.
Well, back to topic, and I think this will likely be my last post since we will start running in circles now:
I don't think the HGB will become such an issue that we need to rework it before the patch. Spending so much time on reworking a minor ability will leave more glaring issues unfixed. The game is better off with other fixes. And if it really turns out to be a major issue, then a hot fix will do in a month or two.
