Your "opinions" as you call them have no real merit seeing as you have not seen how these changes affect the classes.
Considering what they announced for changes, and what they said they were gonna do just before the announcement, and how they are always putting things together last minute... AND how the game always takes the minimalist approach to everything, it's quite safe to say SE has NOT had enough time to fully test this out.

SE didn't even make abilities/spells that go with their initial design from a few days previous.
How is it hard to believe we can't trust them to deliver a balanced system?

I'm not even talking about FFXI, I'm solely looking at what Yoshida has done multiple times, and looking at the most likely probability.
