lol level sync is fine, people will always go for the best ways to level up and nothing will change that. People already only do the best leve's so level sync isn't going to change anything their. Stop worrying about what other people do with it and think about how it could improve playing with your friends. The pro's of level sync far out weigh the con's.

On a side note I had no problem getting parties all day in the dreaded dunes today on FFXI all thanks to level sync ^^
