I intentionally don't level all my jobs, just so I can experience what leveling with be like in 2.0. I thought I heard the devs talking about slowing the leveling pace down after 2.0's launch. That may consume content too quickly, if it's anything at the current pace; especially with a multiclass based game.

Besides, there won't be much exp to gain via PL for normal grinding, it's going forward to leve/quest based leveling like in WoW.
