The best thing about Guilds in Everquest 2 were the "Guild Writs", that people could do to gain status for the guild and have the guild go up in levels. So the more people in the guild, doing these quests, the faster the guild would level.
So in short - I would like a .8 patch to be all about Guild love - including:
Guild Levels - Up to Guild level 50
Guild Quests - To gain "Guild experience",
Guild Achievements - Gained through the guild quests, ect.
Heres Hoping!
