PS4 controllers are just bad from my personal experience. I've had two controllers just miss up on me. My first controller would just sometimes walk left. Like the analog would stick or something. And if I was holding R2 is was worse. And if you played FFXIV as a caster, just walking randomly is bad. This controller I have now is messing up. Sometimes it won't register a hit and then it's register like 10 hits of that button.

And for reference I still have the same controller that came with my PS2 that works fine. And I got that limited edition Lightning Returns controller for my PS3 that still works.
