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

[Lemuria]

BLM still choose between their skills depending how many enemies are on one place, how much MP is still there, how good the tank can build enmity, how long the fight would last.

1 choice less is not the same as no choices.

Black Mage gets what exactly? Spam fire until MP depletes, swap to Ice, go back to Fire once you've regened MP. Toss in a Thunder DoT for good measure when it drops. That's not really a 'choice', it's a rotation. And once you get into a rotation, it's pretty much the only way to play the class. Other jobs work in an identical fashion with their own rotations, excepting healers who at least are a bit more proactive.

I was absolutely furious when they removed half my nukes on Conjurer. This was, at the time, combined with a massive MP hike on spells meaning that I could literally cast only 4 cures before I was utterly drained. Still, I would have traded ALL of them to Thaumaturge if we'd still have something that still resembled a proper Black Mage.

As long as it's not the Black Mage from XI where all you did was spam Thunder IV until out of MP then rest for 3 minutes. So much more complexity than this game...
