That excuse has been used for WAYYYYY too long now!!!
This was July 2019!!
I came to the conclusion that is a bollocks excuse. Ana has been the most picked hero in the game for a very long time. She only briefly dropped this status when the devs buffed Baptiste to allow him to compete with her, making him extremely OP in the process.
Ana needs nerfs. She has been OP for an extremely long time and she is the sole reason the meta is stagnating.
