Specialist System in 3.0

[Aeyis]

It's actually starting to annoy me that gil in this game feels a lot like the how gold was in Diablo 2.. Repair bill, use for a little bit of gambling.. then nothing else, you just stockpile and let it sit.. I didn't get into crafting just so I could make gil and sit on it

I disagree with that. There's a certain something to looking at your gil count and seeing an 8 number figure.

However, I think pulling back to a WoWish style where most people have a couple crafters capped (assuming specialization circumvents the necessity to ding 50 on all 8 crafters) I think you will see more people crafting and as a result making money they can spend.

Hmmm, personally I would dislike that. Not the thought of having more people craft; but the thought that everyone takes a one or two crafting classes because it's easy to level and to do. It would trivialise crafting as a class, I feel.
In WoW nearly everyone had maxed professions, and many had all of them maxed. There was no effort involved in doing so.
I don't think WoWs system can really compare to FFXIV with or without specialisation because of that lack of effort.

That said, I don't see how crafting can take that direction with specialization, as people would still have to level the classes (perhaps all of them) to 60. How is that any different from what it is like now?

If crafting equipment becomes specific to classes again, as well as abilities that would make it a lot easier for someone new to it to jump in. But that would have the side effect of making crafting a lot less interesting to those already into it, as a large part of the fun in crafting is using all those different abilities.
