predictions on new patches

People who think 5th job advancement is coming out don't even realize that 4th job advancement is the final job advancement.

Yeah, it's the final advancement. But they could easily make it so that there was a way to increase your powers further than was previously thought possible, which would be the 5th job

If they did make a 5th job, hypothetically, I think they should reduce the amount of needed experience, while also making you gain much less experience per kill. So, you go back down to needing 1/5 the needed experience, but you only get 1/4th the experience.
