Priest's mindcontrol

Back in vanilla as a priest if you wanted to have a peace treaty with the opposite faction you could MC them then cast fortitude, giving them the buff. Believe this got changed sometime in MoP and the buff will disappear after casting. This just gave a bit of flavor to this class and was wondering if it could make a return.
Or you can mc them into lava, off of a boat into fatigue waters, off cliffs, or into packs of elites.

Nelfs would probably be a good time with shadowmeld.
Mind controlling people off the cliff in Thousand needles= best time ever.
MC off the boat from BB just before the loading screen or just after... death from fatigue and need to Graveyard res... ;)
You used to be able to MC a player and then talk in /say and they would understand you. It will only be a one-way conversation unless you were both priests though. I had a chat with an alliance priest with my undead priest after a good fight in vanilla that way.

Also, MC'ing fire casters in LBRS and using their "Flamecrack" ability was awesome back in the day.
MC is one of the most underesetimated spells. I have always loved it. There are too many fun ways to use it in vanilla to mention. I also loved the expansion when we could use it as death grip, just to stun the person as they wondered what the hell just happened to them.
For questing I used to look for 2 mobs together. I'd MC one to attack the other. When the MC finished I'd finish off the almost dead mob and then fight the one I had MC'd. Worked great on those dark iron dwarves as lots were in packs of two.

Loved MC'ing in bg's..AB was my favorite..MC off the lumber mill .

Between MC and levitate I had a blast in bg's.
Cannot wait to play my spriest again. I stabled her at level 100. The legion changes were just not to my liking at all.
