I have two points.

1) Esuna is completely meaningless in levelling. One can skip by Esuna in getting CNJ up to 50, and not once in my level to 50 CNJ did I ever go, "Gee, I wish I had Esuna right now". Or even Presence of Mind. Blaming powerlevelling is completely meaningless as it's possible to get to 50 the "normal" way (grinding monsters as a party or doing leves) without ever needing either ability.

2) It isn't about the speed of levelling, but the content. In modern MMORPG design, all the level means is what level content the character can handle. It isn't getting to X level to enjoy Y content, but it's about enjoying Y content because I'm X level. It's why MMO's such as World of Warcraft and Rift are so successful.

And yes, the OP was being a douche.
