PvP - be able to attack players every hour. If attacked chances of items are damages yes, but be cool if maybe a Item gets Un-equipped.

Skills - Duration times need to be adjusted for Hourly stats. Maybe 1 hour time on and a 10min cool down. Add skill to join future Raids for SET hours. user input the hours and depends on the amount of hours is the COST of TURNS.

Guilds - Guild Wars for Cash, Steal other Guilds Vault Items @ random not every attack

Quests - As usual, be nice to group all Guild Raids to 1 page or have a map to them with information about what it drops.
