WG is sooooo fun with 5 dks. City defense is fun as well.

Run into a raid unflagged..

Drop army of dead x5
Drop Death and Decay x5
Flag by smacking the best healer you see with a round of silence, diseases, chains of ice.
Then Pestilence, when blood boil goes off the raid starts wiping unless they were smart enough to start CCing you right away.
This works amazingly well against city raids.

In WG I tend to sit off to the side of the other factions main raid shaving away stragglers. It looks sort of like if you use the eraser tool in photoshop ;)

What more reason do you need? :)
