Do you know how quotes work? Because your things are not Quotes
I never said this is the case. I said since Zarya gets played more often Ana is good too. Why? Because Zen is a bad partner for Zarya while Ana is one of the best ones. But despite not saying it, Anas matchup against Zarya is better then the one against Dva or Sigma ( I dont say Ana counters Zarya, but Offtanks in general are all good against Ana exept Hog and other Offtanks counter her more )
I said she is better, not more picked. In higher elos Mercy gets replaced with Brig more and more, due to her abillity to shut down the enemy Tanks and Tracer combo
This is the only quote you got right. Ana is good if you play Zarya in your comp. With Ball Zarya you can still pick Zen if you want, but expecially with Winston Zarya you really want the Ana for the early Nano
