I came back 3 or 4 days before patch.
so I decided to go LNC..and started at lvl 1
got to lvl 10 in about 2 hours

came back last night after the patch came live..
did my 8 leves.
got lvl 12
and I've been grinding all day , I'm finally lvl 20.

what else is there to do to lvl other then behests?
and stupid waste of time side quests..(that I've done for Grid and Ul'dah)

I'm sorry but unless I got a group with me..I'm not gonna grind to 50..
