Not exactly. What the TC is suggesting is for more radical changes to how the overall system works, such as having classes eventually use different types of gear to fill into their newly established role in a party. It's not like with SMN and SCH where they just share the majority of their skills, TC wants to even have the skills act completely different, possibly even have different animations and attack names or whatnot.
Personally I'm all for this, but the way the dev team is approaching jobs now, this is nothing more than a fleeting dream.
