Me and a couple LS buddies are going to be starting a static party when we hit level 50. So far we have...
41 THF/NIN (me)
45 RDM/WHM
40 DRG/WAR
I suspect we'll probably want to get it going around the end of September.
I've got a couple other LS members who are interested, but they aren't really close to 50 yet so I'm waiting to see what else is out there. Post your job and current level if you're interested.
