When we only have 7 supports and two main healers of course ana will be good. She has both utility which a lot of other supports are missing or got removed through nerfs and high healing due to her nade.
The powercreep of DPS heroes has put a lot of our supports in the dumpster because instead of buffing healing or utility they nerf it. Brig changes, mercy changes, baptise changes.
The only support they’ve actively been buffing with good changes is moira. She is the only support able to outheal DPS powercreep at the moment that is AOE. Not single target.
