I think the thing that really sticks out about the constant Mercy changes to me isn’t even that she’s getting a rework - those can be good, just look at Symmetra, but that these are reworks tailored to a certain segment of the Overwatch player base that seems to have disdain for Mercy at a ground level and probably won’t be happy until her mechanics are removed entirely from the game.
You could see it start at the beginning, when Blizzard originally announced a rework because they decided that her play was too “passive” and encouraged her to hide in a corner telling all their teammates to die on the point. This is not something a lot of Mercy players ever did, I think a 1-3 person Rez was way way way more common across all levels of play (just look at the stats for how many people even had the Huge Rez achievement!), but it was parroted enough by professional streamers and picked up by the competitive Overwatch community and repeated ad nauseam until it was eventually just accepted as fact and eventually validated by Blizzard.
Then the rework came along and the same people that pushed for the changes spent weeks dunking on Mercy players for being nerfed, popular streamers would troll people who wanted to play as her, etc. And a lot of people were totally fine with that, they thought it was funny. Of course, the rework actually ended up being very powerful because Mercy players were actually good at the character and the rework added a lot of utility and mobility options for players who were already used to using their Rez and GA, which went against the narrative that Mercy is low skill. So now she’s overpowered and needs to get knocked down. A lot of players seem to think that Rez has no place in the game entirely, and I think that’s going to be the next thing they push for.
This went on a lot longer than I intended, and a lot of it reiterates what really smart folks like @AppleCider have been saying for a while, but basically it’s a real bummer that Blizzard marketed this game as a multiplayer experience for everyone but is increasingly targeting the game to the smaller, more “traditional” competitive FPS community. For a company that says they want to deal with the toxicity in their community every change and rationale they’ve given for the balance lately seems to do the exact opposite. Overwatch as a welcome and diverse place with characters that appeal to everyone and can be effective and powerful even in the hands of people who don’t traditionally play FPS games was a great experience. Overwatch as an increasingly competitive e-sport just makes me want to play Destiny.
