Rein goes in and out of the meta. Ana does not.
I made this thread 9 months ago, complaining about how Ana has been 1 of if not the most picked heroes in the game for over a year.
She has currently been overall the most picked hero in the game for the last 6 months, according to Overbuff.
She only briefly dropped out of the meta when Baptiste was made OP, other from that she has been pretty much the most picked hero in the game.
I am not even kidding when I say that, I wish I was.
Ana might “technically” be balanced but she is still stagnating the meta. She is not like Rein! People have literally wanted Rein buffs when he wasn’t getting picked but literally with zero changes he became one of the most picked heroes in the game.
Ana on the other-hand hasn’t truly stopped being meta since she received her healing buff on her ult. Unless you include the brief period with Bap.
