Since launch I have been in the "no issue" crowd, but I have an update...
I'm not sure what the cause is, but it seems now from personal experience that there is definitely something different about how the sticks react to the way certain people hold/play the controller...
My grandfather passed away a few weeks ago so a lot of family was in town that we don't see much...so I was watching a couple of my young cousins one day and I've gone since launch with not a HINT of wear on any of my three DS4's....within a half hour of them playing Resogun (they wouldnt stop playing that game lol) the rubber on my wave blue imported UK DS4's left stick started to peel off...I was shocked...
I knew I shouldn't have let them use "my" controller lol...but it def seems that it was something specific that one of them was doing that caused it
