That is in fact a lie. According to Overbuff, Mercy heals 11k per game in Grandmaster (the highest tier shown). Ana, in GM, only heals 9.6k. And while Mercy doesn’t deal damage you forget that she can boost damage, which adds a lot to the team.
Mercy has damage boost as well… making them each bring two core abilities to the fight.
Now this one is just my opinion, but I’d say that bringing back someone from the dead, bringing them into the fight, and cutting down their respawn timer, isn’t comparable to anything else in the game. Nade can boost or null healing, which is great, but it isn’t anywhere close to Resurrection.
While it can be the strongest, it is one of the hardest (because of the hitbox and aim requirement, many heroes have easier CCs, such as Hammond, Sombra, Mei, etc.) to hit, and it can easily be messed up without the proper communication.
That’s an opinion. Nanoboost heals a single target, provides damage boost, and provides damage protection, once again to a single target. Valkyrie not only heal and damage boost the entire team (or at least a few allies who are close to the central target), but her healing is increased (60hps instead of 50hps), and she has infinite mobility, able to fly, and zoom towards allies (alive or dead) at insane speeds. If I were choosing an ult to have, I’d honestly choose a Valkyrie.
Mercy has to rely on teammates to protect her, which is why she has the mobility to escape. Ana has tools to let her take out whoever is attacking her, which explains why their deaths are so close. Ana takes out her own targets, Mercy gets someone else to.
That is more or less true. She was competing with Reinhardt for a while, but with the new Meta change and whatnot his has gone down quite a bit. Ana does have the highest pickrate for support, though.
Even though Ana has twice the pickrate, her winrate is barely ahead of Mercy’s, which goes to show that even though Ana is used a lot more, she isn’t able to win as much (if she did, her win-rate would be significantly higher).
You failed to notice that in the all statistics page, Mercy has a higher win-rate than Ana. If you don’t know what this means, let me explain. You’ve been using Grandmaster statistics, which is great and all, but only 1% of the playerbase is in GM. Ana shines in GM, because her higher hps compared to Mercy. So, if Ana has a higher HPS, how is Mercy winning more games? It’s because Ana requires aim. Mercy can hold down her healing beam and lock onto a target, for easy healing. Ana has to aim every shot. If she misses, 70 hp is immediately lost, significantly lowering the amount of healing she can deliver.
In conclusion, Ana and Mercy are practically equally powerful, it’s just a matter of ranking, and the current Meta.
P.S. If you look at Bronze, Mercy has a much higher usage/win rating than Ana does!
