Personally I like to have many skills. Yet in FFXIV I don't expect to see more skills incomming, if it happens, than only on a low-key based cours of time with not more than 1-2 Skills for each job.

While it's no problem to handle many skills for PC users with their Hotbars, FFXIV has always keep an eye on the PS3-Players. The abilitys of a controller is limited and I can't think of a way it would be possible to handle a horde of abilities like in WoW with a controller.
