One of my favorite teams is the single druid 4 rogue team.

Druid is main, he runs in as bear and runs through target, 4 rogues are on follow so they stop in perfect position to attack targets back.

Druid holds aggro untill rogues rip it away, then shifts and goes into healer mode. or if the fight is almost over just goes cat and shreds target.

This team does have a host of problems but I found pvp to be fun as hell wuth 5 stealthed characters. 5 attacks on someones behind is the ultimate one shot.
