I feel this sums it up perfectly.
Sync is a nice feature. I haven't used it but I know people that do and it's a good thing. If I was going back to level some other sub (which I will have to here soon.. need both /dnc and /sch...) instead of having people out of range in my party and killing xp I'd suggest to level sync.
I don't think it should be your first option, I think it should be a final option. I don't think everyone is using it as intended. They are just skipping over people their level to grab "better" options for their party.
Edit: I would like to take this moment to say that I think most discussions can be solved with a lolcat. That is all. Edited, Oct 17th 2008 8:08am by ZelgadisXI
