I'm curious to see how materia will be scaled in sync party. I remember back in FFXI I'll do a /sea to check for people seeking party invites. Most of the time I see "No level sync" or "level sync 50+ only" It defeats the propose of its function, but it does work well with friends, and it can be exploited like smn burn pt.
My feelings for level cap is... neutral. will most likely avoid it unless I really have to play it.
