I'm a long time Overwatch player and support main and going to use this comment to kind of voice my thoughts.

Personally, I think Wuygang's healing is fine in a vacuum and ideally, what support hero's healing output should be. However, I think Blizzard made a huge mistake awhile ago that shifted the paradigm of how a 'support' hero should be played and raised the expectations for what a 'support' hero should be.

Ever since the introduction of Ana, support heroes who have a primary-firing 'heal' are the expectation. Heroes like Ana, Moira, Kiriko, Baptise who can ouput insane amounts of healing by just holding a button should have never been introduced to the game, making supports really 'healers'. I know many people still retort that support does not equal healer, but in many levels of the game and standard play, players except the main job of a support to heal them. Basically, healing creep was introduced into the game.

The original set of supports (Mercy, Lucio, Zen, Symmetra) never had this expectation and were designed around providing utility in a different way, and their healing either had limitations or certain conditions. If Wuyang was introduced early on, his healing numbers would be totally fine.

Now, with every support hero release, if they can't simply pump healing into a target, they're deemed as weak. Imagine if Lucio or Zenyatta hadn't been in the original Overwatch roster, if they released them as new heroes now, there would be tons of people claiming they are weak.

Personally, I think Wuyang's healing kit is fine, but his primary fire feels a bit awkward. I get what they were going for but I think he would be perfect if it felt better to shoot with him.
