Does ANA trigger a vicious circle in Overwatch balance?

According to devs, Anti-heal mechanic is the guarantee of the overall healing not getting too far out of control.

But since the launch of Overwatch 2, ANA is showing her domination cause it is difficult for one tank to get survived if being naded.

As a result, tanks without shields, say Queen, Roadhog, Mauga are having a literally poor game experience when fighting against ANA, which forces designers to boost their ability stat in order to have a healthy picking rate.

And it makes these tanks seem too powerful when the enemy team have no ana, which in turn grants ana an irreplaceable high status in rank. Does it sound a little ironic?

EDIT: I am a support player used to be an ANA main in OW1, but I am fed up with my teammates accusing me of NOT PLAYING ANA or urging me to play ANA or WE LOSE.

I play at Korean Server and I'm at Master tier presently.
