I’ve been seeing a number of posts from newcomers to the “mercy discourse” that suggest a new E ability. This in of itself is really cool, and it’s great to see more people interested in the idea of reworking Mercy!
A common suggestion for an E ability is powering up Mercy’s staff in some way, and/or a mini Valkyrie. On the surface, it makes sense. The Mercy community already calls Valkyrie an overhyped E ablity, and a common complaint pre-rework was about her lack of independent mobility.
However.
I’m sorry to say it, but a mobility ability and/or a beam powerup in the E slot at best won’t fix the problems with Mercy’s design, and at worst will bring back Mercy 1.0’s problems but worse.
Hear me out for a second: Let’s talk about the SR system. It had no idea what to do with 1.0 Mercy, because there weren’t a lot of stats to calculate. The only stats Mercy has any solid control over are her healing and rez count - damage boost depends on your teammate’s performance, and Mercy’s pistol is meant to only be used in niche situations. This lead to the system putting too much emphasis on rez count when calculating SR gains/losses. Once the playerbase found out about this, a few stat padders ruined the game for the rest of us.
If you put mobility or a beam powerup on E, then the system will go right back to giving disproportionate SR gains/losses based on ult stats (whether it’s rez again, or something new).
If Mercy is going to have a kit that doesn’t reward bad player behavior, her E abilty needs to give performance calculators new stats to chew on. Something new and unique, that can be quantified with numbers. It’s the only way to dilute Mercy’s appalling dependence on rez (or whatever else is her ult in this hypothetical rework), both stat-wise and in player perception.
If the devs don’t want Mercy to only be known for her rez (as they have stated), then they need to give her more to do than "flying around with beams and rez."
Addendum: as far as mobility goes, the bunnyhop and superjump have already has done wonders for Mercy’s fluid movement-based playstyle. If the superjump was made an official part of the bunnyhop tech (and maybe upgrade her passive featherfall into a real glide), then Mercy would be set.
