How can "overnuking" be a problem ?
Let's see...if you fight one big monster, Primal style, you'll aim for the most DPS, so you can't overnuke.
If you're figthning some trash mobs, leve style, you can wait, what...20 seconds until your MP refill enough to compensate any spell cost.

And, please, stop ranting...BLM IS NOT AN ENFEEBLER (By the way RDM isn't supposed to be, too). We don't have any real enfeebler now, but guess what ? There's room for several more jobs.

Do you rant because Dragoon don't have a pet ? Not that it ever had any besides FFXI. Do you rant because no class can dual wield ? Let the classes come. They were redoing the game, so, of course they won't implement a new class for a game that is supposed to bet "replaced".

Maybe I need to remind you that party size was 6 people in FFXI. Basically, you had to open all possibilities with 6 jobs. Now, we can gather 8 people, so we'll have room for a real enfeebler when it comes out.

So now, you're playing a nuker, only a nuker, like BLM is in almost every Final Fantasy before. Worse, signature spells were Fire, Thunder and Blizzard for the vast majority of games, too. Besides FFXI, Stone and Aero HAVE never been Black Magic spells. Final Fantasy XIV is not FF XI's successor, and it's good that it finds its inspiration far more in the roots of the Final Fantasy franchise.

I won't rant about "blah blah you want FF XI-2, go play FF XI, etc...", but really, FF XI is still up, and I'm sure it still has a lot of things to offer. FFXI point of view should stay in FFXI, as it's what made it stands out from other MMO.
