If they dumbed the skill system down any more, people would complain its too simple. GW2 for example, binds each tier of a skill to the slot of the first one. while this is nice, it also doesn't have a very complex skill system, and you can't make use of most of the skills in that game unless you are specced a certain way.

Maybe this is a problem in XIV that exists for only some players, but I've never thought that I had just too many skills. Maybe its only something that occurs on certain classes.
