Played all MMO's with Keyboard/mouse and when I first got FFXIV i started with the controller, it was nice it was responsive and was definitely a great way to play.

However I then went back to my PC and keyboard/mouse and honestly, nothing compares. I will do casual raiding on the PS4 like WoD and my crafting/gathering and fates etc, but for Final coil its keyboard and mouse all the way. I much prefer the precision.

It is all down to preference, i also have a razer naga which just makes PC gaming a dream.
