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

Something that would help with the "depth" would be to put the elemental wheel back in. You know, make it so you would heal Ifrit if you hit him with Fire, you can kill the undead with Cure. I miss that...

So make BLM utterly worthless in Ifrit. I like this idea.
