Based on my experiences in the past few weeks for Mid-to-High ladder, Mercy is never picked anymore. Maybe every 5-7 games, but not as extreme as Ana. Ana’s kit is maybe a little overmeta anymore, since most people in the division has meh-ish aim, and tanks are so HUGE that it’s nap time for me every time I initiate, and the hitscan burst healing that Ana does just out-damages pretty much every burst anymore. So pocketing with that massive healing on a dived teammate such as a Zenyatta (who still has that +30% damage “cooldown”) can destroy a comp, the only way to get any kills anymore is just waste a teamfight and hope to god that they don’t know the flank, just to dive the Ana way behind the point. Just like a Widowmaker who’s dominating the team by staring down the choke hitting headshot after headshot from a perch 500 miles behind her team.
Mercy is in no way meta anymore unless Pharah is picked, and again, the sniper renaissance has kind of destroyed that strat. The only thing keeping Mercy alive at the moment is Resurrect and the consistant healing beam, which the Devs nerfed the output of, making the game focused on DPS/OrisaHog/Support burst if not the current GravDragon, or Stun metas.
Valkyrie is a great ult to initiate, but can be shut down by Ana with that bionade of hers, as well as it’s unfun to play in it. Basically it’s just an area of effect beam with the ability to fly. Which is easily shut down with Duck Hunt Widows and Anas against Mercy. Valkyrie is mostly ineffective against burst which is nerfed due to the fact that you still don’t generate more healing in it than you do normally.
The fact of the huge Ana buffs, the Mercy nerfs, and Zenyatta inaction causes a perception of “skill” buffs. But only high damage heroes like Zarya, Hanzo, Widowmaker, Reaper, McCree, Hamster, Zenyatta, Doomfist, Brigitte, Tracer, Orisa, and Roadhog will be able to cut through Ana’s healing and bionade unless another Ana is effectively shutting her down.
Consistent damaging characters like D.va, Winston, Reinhardt, Sombra, Genji, Mei, Lucio, Soldier:76, Moira, and Symmetra’s Beam won’t be viable until their burst cooldowns are reset, because burst healing is extremely powerful.
Zenyatta is still okay because he’s kept up by stronger healers. He’s basically Reinhardt in the GravDragon meta when it comes to viability. He is flexible with most comps as is. Lucio’s ult needed the buff, and he will be used much more because of it, and Moira is an excellent healer/DPS to take if you need powerful healing in short amounts of time with a highly mobile comp. Just Mercy is in the basement anymore, the consistent healing isn’t enough to keep her on her throne of best healer. The Rez is the only thing remaining to send her into dumpster tier, and knowing the community it’ll probably be removed once the developers read the overwhelming dissent produced daily about the ability.
I really hope I’m just making a fuss over nothing, because I love Mercy and D.va’s playstyle, but if they keep buffing “skill” like McCree, Hanzo, Widow, and Ana… Then both will once again be in a garbage tier only used for abilities like Defense Matrix and Resurrect.
