Weekly server wide quests would be awesome as in Asherons Call 2 Chaos Eidelon quest. The whole server would gather in Cragstone, take the chaos plains summon, storm down the gates of the Chaos Eidelon for a nice hefty reward. It was always good fun to see the whole srever come together to crush a boss.

Would be fun to have similar type of quests in this game.

Ok , just my random suggestion.
