I played FFXI with a controller so when FFXIV 1.0 came out I kinda carried that over and made use of their similar macro system to do the same kind of play style.

After 2.0 the new cross hotbar system came and it took a bit of getting used to since it was slightly different from FFXI type macros, but once I did I find it great. I've played WoW and I used KB/M strictly for that (not sure if you can even use controller on WoW), I did PvE and a lot of PVP and it was fine, but I find the controller is way easier on my hands and wrists than KB/M.

It just seems more relaxing and comfortable to use controller, if I stay up late I can lie down or lean back and if I have to type I can just prop up for a second. If you can get used to using a controller effectively in this game you might get to like it ^^
