Well... if people wants to level the lame way it's their choice. I want to help low-level people doing content they can't do because there are so few low-level people, and that being my choice I gladly support the Level Sync.
As for now, you could just take a L1, go to Treespeak on its East and Power-level that L1 until L40, then going to a Stronghold and make its way to L50.

By the way, can you guys explain me how can a party that is the same level getting powerleveled in Level Sync? Sorry if I don't grasp this concept, but I'd like to understand, since I never power-leveled in XI. Thanks!
