Well the other factions don't really need to use TDs as much as USF,
As soviets i usually go T-34/85s if i want a bit of fun, or ISU if i really want an easy win.
As ostheer i see most of my opponents go P4z mass or tiger with mortar ATG support
As brits its really all over the place and on top of that i don't really see people playing it, its a boring faction.
As Okw p4j or double panthers
As USF i usually go Sherman->Pershing or Jackson--->Calliope.
Thats just the meta of the game right now. And the meta for every faction will always be spaming one type of unit or upgrade. (Like g43s for ostheer, or the old double LMG riflemen <---- these guys were true liberators)
I am speaking from mostly 2v2 experience here.

The Jackson may be overpowered, but i say wait for more time before making it a fact. A lot of people in this thread seem to being having a knee jerk reaction(me included). I as a USF main player disliked the old Jackson. One mistake slight mistake and any other tank in game could rush you down and destroy you. The new Jackson is a breath of fresh air in the USF late game for me now. Something i can use in my arsenal to finally go toe to toe with late game high armour tanks which USF as a legacy for struggling with.
I propose that we wait and see for another month or so before dropping the hammer on the issue.
