So... that spiderman shirt... (new job tease)

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.
