If SE decides to add NPCs that are certain class not in the game yet but will be later in the future of FF14ARR contents how will you react.

Will you flip tables because they confirmed the release of these classes by release NPCs that are these new class but say "Nope you can't play as these classes yet until X.X Major Update or X Expansion but here are some NPCs that are these new upcoming classes"?

For example, if in 2.4 Main Story they have you fighting along side a Scout NPC( class that goes into Ninja/Thief) who is a new major character being a veteran member of the Scions we have not meet before and this NPC happens to using a certain amount of Scout skills because he or she is a Scout class. However, you can't access Scout class yet because it is, assuming, planned for 1st expansion which is most likely released after 2.5.

Or

They have you meet and fight along side a Melee Mage class NPC who use skills from the Melee Mage class during the Main Story of 2.5 as their way to tease about the release of a Melee Mage class in 1st expansion while having this new NPC as a minor or major character we will meet again in 1st expansion storyline.

(Remember this is a "IF" question.)
