There can be a lot of skills in those games and I wouldn't mind, my main problem with "too many" skills in FFxiv is that the battle system aims to make us use all of our skills, so we are required to have all of them on hotkeys. Especially with a controller this can get annoying at times, requiring a lot of trial and error to find a setup you're comfortable with. Personally I aim to have 2 hotbars for active play and a third for more supporting skills (aka skills you don't use all the time, for example those that you switch on at the start of battle then don't touch anymore), potions, food,...

Other games have shown a different approach, giving players a huge pool of skills to chose from and design their own build. This is especially attractive, since it encourages individual setups and makes people try out different things. Of course there are always skills that are considered as mandatory for certain classes, but in general you'd have more variety with that setup. As much as I'd like to see FFxiv go into that direction, I think it unlikely it's gonna happen.
