Hey there,
If you are looking for GMT based LSs then I have a few that I know of that might interest you people...
If you are looking for a Social LS with alot of Helpful, fun and chatty Players then you want to look for a LS named Honorbound. I am currently residing in said LS at the moment. If you hit me with a /t in game I'll see if I can sort something out. :) (Ciaranjgw in game)
If you are looking for an Endgame LS then may I point you towards my former Endgame LS named GrailofDestiny. They do an number of things. (HNM/ZNM/SCNM/KSNM/Sky/Sea/Limbus/Salvage/etc) The LS itself is aged and experienced. Alot of Skilful players in there. They have NA players there too.^^
If you want to join it the go to
http://grailofdestiny.proboards55.com, Read the rules and make an application if it sounds like the LS for you. :)
I hope you find this information useful. :)
