As a controller user, I think Viper is already at the limit of what most people can comfortably handle in terms of APM on controller without making the job even simpler. I know this because I'm a crazy person that plays WoW on controller and I mostly have to stick to classes/specs below 50 APM because 2 thumbs can only do so much in comparison to M&KB users. I do play fury warrior which is one of the higher APM specs in the game sitting at 67 APM, but it's the only high APM spec in the game that's feasible on controller because it's simpler than even viper with very few OGCDs. Now Blizzard doesn't have to design their specs around me and the 10 other people that play the game on controller because their game isn't designed around controller, but FF14 does have to think about us. And for as simple as fury warrior is, I still get major hand fatigue from playing it.
