I somewhat agree, but part of leveling up and learning new skills is learning how to USE those new skills. Being thrown everything at once can be confusing if you have a lot of skills. Current WoW wouldn't really have that problem, but FFXIV absolutely would. So leveling up while learning the new skills allows you the time to put those new skills to use before you hit end game helps you understand their use and priority, etc... easing you up the learning curve.
Tutorial may not be the absolute correct term, but for all intents and purposes, IMO it fits.
