No. Merciful Twelve, no. I'm -very- happy with the XP curve the way it is. Admittedly I'm the 'ideal case' of "doesn't actually get to XP that often, so I have time / alternate jobs that I wind up doing quests on at the appropriate level", and I love it. I also love knowing I could grind something to 50 super quickly if I wanted, or 30 for an ability, or... whatever. I love knowing that leveling pace actually -doesn't- suddenly slap you in the face once you hit 30 like this is some kind of Korean grindfest. AoE spamming mobs to death, while I've actually had a lot of fun in a perma with friends, is not and never will be content, and if I want to do Toto-Rak on a 'level appropriate' class I can grind CNJ a bit or something.

If you think leveling is too fast, then, uh, slow down! Nobody's forcing you to get XP as fast as humanly possible. Seriously, I completely fail to understand why people seriously say "XP curves need to be steeper". I /like/ XPing and I still prefer shallower XP curves. "Back in my day we walked uphill to school both ways in the snow and levels actually meant something" is not a valid argument. Sorry.
