I feel you. It happens to me so often that it genuinely impacts my matches.
I play with a PS4 controller. The issue has occured both on PS4 itself as well as on PC (via bluetooth/DS4Windows and via usb cable/steam controller overlay). My ping is around 17-20ms. I've updated my drivers.
It explicitly happens even when I'm not stunned, silenced or otherwise CCed and when I'm not animation-locked. Often times I'm quite literally just running or
standing (without a status affliction/CC) while mashing a button but nothing happens. Oddly enough I DO see the button input (that visual ingame cue on your hotbar when a button is pressed) in those instances. It just doesn't translate into an effect.
It can affect every skill but I notice it particularly often with my
- LB --> Often I have to press 4-5 times before my LB activates (again, even when not stunned/CCed etc.). This is particularly frustrating when you want to time your LB but then you just stand there next to your opponent very un-menacingly for 5 seconds.
- Sprint --> It will sometimes straight-up not activate for the first few presses even when the only thing I do is running.
- Recuperate, guard and purify --> I feel like those often don't go through in particular when I'm under fire so I wonder if the game can't compute/process/[insert correct IT term here] so many actions coming from different players at once.
It is super frustrating when it happens with purify. Frequently when I'm CCed purify will just not react (and then I die because I couldn't break the CC in time).
- Palette swap (on pct)
Those are the most egregious ones for me. I guess I notice it with those skills the most because it hurts the most when they fail. But it has happened to me across all jobs and all actions.
Valence pointed out it might be when there's a lot going on and I do feel as if those circumstances exacerbate the issue a lot. In very busy moments where lots of players use lots of actions in one spot the reactivity of my buttons gets noticeably worse. But it also happens in "calm" situations in a match (I'm just running without being attacked). It rarely, if ever, happens outside a match on a training dummy though.
I'm begging you SE, please fix this.* This problem has been the number one issue of my frustration with CC. T__T
It's really not fun to lose encounters or even matches because you pressed those buttons, you did the things you were supposed to do (for once), and the game just nopes out repeatedly.
*(Or if anybody has an idea what I'm doing wrong please let me know. :') )
