Just theorycrafting, sorry, but are all your chars at range except tank and rogue? If so, one bubble and clear bubble off you should stop one fear. One dispel from priest should stop one if you get lucky. One fear ward should stop a fear. And one free action potion should stop a fear I think. Just let the rogue wander around if you have enough DPS already.

For the mind control, can you dispel it (priest)? Can you free action potion it? You can't bubble out of it, probably cause of loss of control of your char. But can the rogue stun lock you? Vanish, cheap, gouge, wait....kidney. That should be 3 points easy (even if he doesn't do any special moves). Would that be enough time to give you time for it to wear off? What about the lock fearing you? In ST Jammal will MC someone, find out what people do there. In SFK, Argul will MC someone, what helped in there. If MC is a shadow spell (go to Thottbot.com and check boss, then check spells he uses and then check spell to see if physical or shadow), you might use priest shadow resist thingy and maybe a shadow resist potion and/or just a shadow resist ring or neck to try to resist it.

If you have a lock, you can summon into instances, you might substitute out the rogue and get a shammy for tremor totem or grounding totem. Just one fight and then you can summon the rogue back in.
