Power Leveling is an flaw and decreses the personal value of a Max level character.

[Travesty]

So what about Role Play is related to grinding the same monsters/leves for hours on end, that isn't the same as being power levelled?

If you want to take things as literally as you seem to, you are gaining experience by watching another person destroy things, thus your character is studying from his master. There you go, some Role Play for ya!

Like I said, the grind does not have to be the same monsters/leves for hours on end. In fact it shouldn't be, because that's boring. But that's a flaw with game design that FFXIV should deal with by making the grind more enticing and interesting through content and game design, instead of largely removing leveling from an RPG, which is just another form of bad design.
