So Why assume removal of Classes?

This has absolutely nothing to do with anything she said. Your class and job are shared - Getting rid of the class lets you expand the job further because all a job is in XIV atm is - Soulstone (added stats), then 5 extra skills ontop of class skills, thus anything branching off of the class will be heavily limited to the class skills+5 additional skills whereas a pure job can do much more and not be hindered.

Look at Blue Mage - The reason Yoshida finds it hard to implement is because it has to fit into the Tank/DPS/Healer role - whereas take XI's Blue Mage, it can fit any role except for nuker (it has no native nukes in the traditional sense) - So classes+the trinity limits things because they either introduce a class and job each time (which he said he will not do) or they slap a job onto a preexisting class, thus heavily limiting it.

Has nothing to do with wanting instant gratification.
