I would blame it on the maps!
The solution here is to just ban the maps that the Jagdtiger is broken on. The Allies never want to play on these maps anyways as they're super stacked for Axis in my experience.
4v4:
1) Ettelbruck Station
2) Faceoff at Rostov
3v3:
1) Ettlebruck
2) Faceoff at Rostov
3) Lazur Factory
4) Angermeunde
Ettelbruck is probably the worst map that has been made in a while. It's the campiest gameplay and a veritiable playground for a Jagdtiger. Flanking is impossible and it is filled with buildings and "shot-blockers" both of which the Jagdtiger ignores and just fires through anyways.
Faceoff at Rostov is fairly urban with (good for Jagdtiger) and just a bad map for balance anyways. The bottom team is always at an advantage as they never have to cross ice to get to the lion's share of resources and VPs in the city. It is a terrible map for flanking as most flanks go across ice or bridges and thus wonderful for the Jagdtiger.
Angermeunde is a playground for Pak43s and Jagdtigers. Any thin urban map is.
Lazur Factory actually isn't that bad. All of the maps above and thin and long which benefit tank destroyers (tank destroyers who ignore terrain doubly so. Lazur is a square map so flanking is possible but only has ~5-6 crossings which are easily mined and covered so it become campy gameplay anyways.
Ban these maps and you can avoid the true bullshit that is the Jagdtiger.
There are still maps that you don't want to go up against a Jagdtiger here. The WFA army 4v4 maps where harassing the enemy's fuel supply is near impossible are particularly bad (I see you over there Lienne Forest!). You don't get more bans for these though so you've just got to deal. You've really not tasted the Axis bullshit souffle' until you've dealt with OKW + Luftwaffe Supply on Lienne Forest. The safest sector on the map is the fuel sector and they can use that to drop 50 fuel for allied forces.
The Jagdtiger is still really good outside of these maps! It's just completely broken on them.
I faced about ~3 Jagdtigers in a game yesterday in a battle on Steppes. It was tough fight but the Allies inevitably won. 290 fuel for the OKW is essentially 435 fuel for another side. Steppes has bad terrain for the Jagdtiger in the middle and flanking is powerful there. A 5-Jackson push kept the Jagdtiger herd nice and thin. It's not impossible to deal with this unit but you want the terrain in your favor to have the best chance that you can get.
I think that there are big balance concerns with this unit. It is obviously broken on some maps and I hate that. I really dislike the unit in general. There's really no counter-play involved with this unit as it ignores fundamental rules to the game. I can't hide behind buildings to flank it because it shoots through anything. I can't really use artillery to destroy it as it can move and it has armor so think as to render all but the heaviest of artillery useless. Heaven forbid I am playing Americans and choose a doctrine other than Infantry. Then I have no artillery options left. The power of the Walking Stuka makes Howitzers a short-term option against it that will never build up veterancy. The only albatrosses the Jagdtiger has is the cost and player stupidity in wielding it.
