Snip.

Easy. BLU would have no cross class skills, and instead would choose from an ever growing pool of monster abilities.

And SMN can just get more and more summons The game isn't designed for that. (and if it did, most of the abilities would be useless, which is the entire reason that skills are being streamlined... they aren't going to add more skill bloat)

Considering that they plan to revamp the battle skills somewhat for the expansion, and given the fact that we don't really know how they plan to restructure it, I'd say it's entirely possible that it could happen.

I highly doubt that the battle system is being changed THAT much, from what it sounds like is that the battle system is being streamlined and made easier to exist in its current form. As well as this is the visual cues.

Easy, you control what the BLU can absorb by only granting the abilities through their story quest.

Yoshi P specifically said that this method does not feel like BLU in his eyes, and he did not like it. He could have changed his mind, but I doubt it.

While I'd want BLU to be added, I'm like you in thinking Yoshida wont actually do it, unless he make something "Almost" like it, as he did with SMN, or worse, AST (Which is Time Mage mixed with Gambler, which was unnecessary, and could have remained Time Mage in its current build. Heck they even made the AF for Time Mage, only to change it into a crafted armor, and recolor it)

But I disagree with your logic.

Looking at FFXI as an example, if you equip spells, you wouldnt have skill bloat, as you'd have a limited number of "Blue Magic" slots. (and some abilities might not be tied to those slots, which are basic Weapon Skills/CDs.)

Next, looking at how equipping spells in XI granted you special passive traits, Id change that into every spell falls into a category, and you need certain "Categories" to complete your chains.
So lets pretend there are 3 "categories" of spells, A, B, and C.
Literally becomes "Cast A type spells to pump up B type spells, and B spells build up stacks for C type spells."
Or how ever they wish to handle it.

My personal interest would be picking between the 3 type of DPS in play style.
Melee attacks with positionals.
Ranged Cast bar damage spells Spells, usually needing to watch stacks.
Ranged short cast bar spells that do less dmg, but offer support like BRD/MCH.

Id then want a limited number of slots for spells which can either give DPS boost (A self Haste for example), a mitigation boost (Mighty Guard for more defense), and a heal (White Wind) and if BLU ends up a DPS like RDM, then you'd use the DPS increase for hard content, but instead equip the other two in more solo friendly encounters.
(Pretty much what DPS do at lower levels, soloing content, needing heals, so they cross class something to help them survive)

in prior FFs, not all enemies had magic to learn, so its not like we need a spell list of 999 possible spells either.
Though my suggestion is the equivalent of making 3 new classes, to which is another reason it most likely wouldnt be made.

There's no skill bloat with a cross-class or FFXI type system of equipping spells, only balance issues. And likely everyone would equip the "correct" Blue Magic spells and there'd be no room for experimentation, but bloat definitely wouldn't be any more of an issue than it is for any other job.
