No point in job progression of this scale if alot of players can't even push past 25% of theoretical maximums with what we already have.

Also FFXIV =/= GW. The jobs don't change names or add exclusive progression abilities with rising levels because jobs are very lorebound. The jobs existed since the first FF game (alot of them at least) and have been continued repeatedly until eventually FFxiv's turn. If a Black Mage was eventually called Wizard, I'd be kind of confused to why they break part of FF immersion in favour of "job progression". It's a dumb concept anyways, just rework, improve or even ADD abilities as needed.
