Not these days.. Even mercy with her nerfs is more usefull than her. She is having a great kit that she almost cant use with all these shields and when the team needs to contest high ground together. Its not for nothing she still has the lowest pickrate on GM matches...
I don't mind Ana at all, but it's quite literally hit or miss. I'd prefer Zen or Moira to her, but if you can nail your shots and make your call-outs, that's great.
Most Ana players cant even aim -.- I play tank and healer all the time, and as a tank, in the middle of the fight, you can expect heals more from Mercy than Ana.
I’m an Ana main with an average of 70% acc. Scoped and unscoped and an average of 6124 every 10 mins. So I’d say that I’m pretty good. You’d probably want me on your team
