What I started doing is a real bitch for the inevitable jackass rogue that wants to screw with you. If they open on your main, its ez mode, just press your universal "move back" key while you're stunlocked. LB and shock until he blows cloak. When he does, use the opportunity to heal the guy he's attacking up to full. Cloak runs out, resume casting. If he opens on an alt, turn your main to face your alts, then use your universal move backwards key. This leaves one alt in the middle, with the rogue faced by three active players again. When rogues become a real pain in the arse is when they move in pairs and threes and you don't have anyone w/ you to help out.
