Why can't we have jobs with this level of depth and customization in FFXIV?

So many useless skills. We already have Cure and Cure II that do the same thing, we don't need 4 more. If this is the kind of "complexity" people want, I hope we'll never come to that.

Cure I isn't useless, it's good when you are balancing threat gain, mp conservation, and healing output.
