People are assuming they are just bugs, but I could be wrong.
Her ultimate comes out delayed. You press Q > see the ‘hand wavy’ animation > wait roughly 2 seconds > the wall goes up. It used to be almost instantaneous when you pressed Q, now you can’t really use it on reaction to something like a DVA bomb.
Her turrets also seem quite janky at the moment, sometimes they straight up just vanish without anything hitting them.
There might be more but those are the only things I have encountered.
"O-Oh no, we couldn’t possibly get rid of the one shot on railgun or the intangibility on suzu. Thats what makes it fun…
GET THAT ******* MOBILITY OUTTA HERE, HAHAHAAHAHA"
-Blizzard, Probably
Pretty much the ones Frost listed.
I’ve also found her teleporter times out faster under kitsune rush. However I’ve only seen it happen once and haven’t been able to replicated it.
Sojourn is busted, so she was beginning to see more play because she makes her more busted.
Servers being laggy even more so than normal (seeing myself in the deathcam in a completely different place to where I was when I died, making sense of me dying where I shouldn’t) and the wall issue really does feel like it must be a bug. It’s a huge delay and removes skill from the equation. And by proxy it actually seems to make the ultimate shorter, since the timer doesn’t start once the wall is actually up, further corroborating it as a bug.
I’ve noticed her turrets disappearing, too, as well as simply not attacking someone right in front of them.
This patch is just broken.
I want sombra’s utility back 
Hotfix for blizzard takes like 2 months, so don’t expect any change before season 4
We got a patch within 10 days in season 2.
Number one way to farm upvotes – claim your someone who doesn’t play Mercy but side with Mercy players on any. change. ever.
There may be tweaking to be done, but Mercy being a fighter jet darting all over the map wasn’t fun for anyone but the person playing Mercy.
She actually takes a little thought and positioning now, and might even be stronger for it.
Wdym this is obviously a science forum where subjective statements have no place. It says “General Discussion” not “Opinion Heap” so we can expect the finest quality of results here.
a joke
people say rez is the core of her character and kit but lets be honest, a snooze fest of an ability to you only use a handful of times a game is not core to her at all in any way. Her mobility is the real core part of her kit, being able to reposition from ally to ally, using movement techs to keep yourself alive…
They overdid it by making the movement techs so easy (they should not have been changed from ow1) so she became really hard to kill and now we’re suffering for it bc they never roll anything back, as that would be admitting their mistake. The only nerf GA should be receiving is to the additional movement like super jump and bunny hop.
Also delete rez its so boring I hate it give her a fun ability
If other heroes can be reworked so can mercy
It doesn’t deserve a patch. It just doesn’t.
You can argue its not “fun” and it “feels clunky” to wait 1 more second to “do the thing” but reality is not changing:
She can get the same results/stats/performance with a 2.5 sec CD.
Its just slightly less forgiving. That’s all 
She’s been top 3 since the release of Overwatch 2, and would have been top 2 if kiriko wasn’t OP.
Just bring back the simple OW1-style GA where you could only jump forward continuing the same direction as you were flying before. Arguably jumping in any direction after a GA does not seem logical, that’s not how momentum works IRL.
As for cooldown, as someone said 1.5s is in people’s muscle memory by now, so not even 2.0s would feel right.
