I'm reviving because of this:
"RPG Site: As far as gameplay goes, how will grinding vs. quests work for leveling? Will players find more reward from taking on more quests as opposed to just outright level grinding?
Yoshida: We will be moving away from a grind-oriented leveling system to a quest/content-driven leveling system. No longer will randomly defeating public monsters be the most efficient way to level your character."

Well we all know how well Starwars did with quest based everything, yep, it's going free to play now.

We can also see how DCUO did with their instances(free to play now), grinding out those in 2.0 should be fun. I mean, all dungeons are going to be instanced.
