In recent interviews (?), Yoshida gave us some info on how the shared role abilities will work.

My question is: what abilities do you think should be pooled together and shared across roles? Naturally, there's a few that are almost guaranteed to be added (Cleric Stance, Swiftcast, Provoke, Invigorate,etc) but what other shared abilities would you like to see? Are there any abilities not currently available that you'd like to see become shared?

Yoshida also noted that physical (Bard, Machinist) and magical ranged (Black Mage, Summoner) may be considered the same 'role' (and thus share abilities distinct to the ones available to melee).
How do you think this would work? Currently there are some invaluable abilities available for Bards from cross-class (Internal Release, Bloodbath, Invigorate), so how do you think physical ranged will change if they do end up sharing with magical ranged? Maybe you don't think it'll change a thing. Will Bards and Machinists be throwing out Eye for an Eye, Virus and Blizzard II?

The casting animation for Physick would look pretty goofy for Bard/Machinist since they hold their weapons in the left-hand (as opposed to Scholar/Summoner who hold theirs in the right), meaning they'd have a grip on pure air where the book should be
