Raids are like things that require multiple parties like 10 man, 25 man and usually you have a couple of boss'es like having some of the old sound bases could be another where you go around looking for clues or something! Instead of every month why not have them available every single day just add new raids like every 2 months or so. Also sorry i play alot of mmorpgs and cap quickly so i always need something to do so far wow and gw2 have me with their new stuff.
Well when i say dungeon and raiding I refer to instance and well raiding, Which in my opinion are needed for players that cap so they have something to do, Also the caravan idea sounds great for a escort mission. but like one instance could be in the land of wave's and other famous scenarios.
I feel like guild's/clan's should have a level system and get rewarded for doing Dungeons, Raids, Pvp, And Questing together! And offer certain skill/perk's as a reward for those clan's/guilds that have gained the level's.
