I have to admit, I am loving the PL arguement. That was a fad before people even realized it, and passed even more quickly.
The only people who are going to PL are the same people who find ways to get max level in everything, and lets be honest (especially on the new servers), they are a) going to be WAY under-geared (you can't PL a crafter or gatherer), b) groups who party level will do the same thing with regular parties, c) They still have to level their first classes the traditional way, d) They need to complete their Job quests, Grand Company Quests, e) They will not have access to the Faction Gear (and pre-craft, Pre-AF, Pre-Dungeon, this is the best gear you can get, and it is far easier to get than: Crafted, Dungeon, and AF, and obtainable 10 levels earlier, and is usable by more classes/Jobs).
And there are many other little bits that make the whole Power-Leveling on the new server strictly for the over-leveling End-Game only people. And literally, the only thing that would change (if leveling wasn't just as easy and far less boring) would be that it would slow them down, but they would still out-pace anyone who actually cared about playing through the game.
Anyways, yeah, I already started a new character on the same server, just to play with it (and in 1 month, I didn't get high enough to get my goobue horn on it... so it's questing for Choco for me:P). And I will probably start a character on a new server just to see what the world is like.
Needless to say, there is now enough in the game that at any level I have been able to stay far more busy than I have time for, and there is still stuff I haven't gotten done (I still need a CC win, and a Garuda win, and 1 more Gold Key NM for sure)...
It really is impressive, at this point how different the game really is. If it wasn't for all the glaring problems still in the client (random crashes, load issues, the Retainer system), it would actually be an impressive game in it's current state. With that said, I have grown attached to my character, and while I will miss it when the servers go down, I think I will skip out on the private beta, and maybe come back for a peak in the public beta, but really hold off for the release, so I can start redoing the storyline quests, and explore the new world (one of my first goals is always explore everywhere first).
