Were. P47 got nerfed consistently. Its pretty dang close.
But the ways to counter it are not close. The AA HT costs less, has less pop and comes earlier + it is also a defensive unit so you could put it in the back.
The 222 which comes at around the same time is no where nearly as consistent. And Ostwind comes far later and without vet is not as consistent + both of them are not defensive units.
In terms of pintles both OST and AEF have that option so you cant bring pintles as deciding factor.
USG also has doctrinal m5 as well.
