All right, here's a funny thing I discovered when I was bored in Shattrath.
First off, there's an NPC called "Vindicator Kaan" over at Aldor.
If you're Scryer, he's hostile and you can pull & kill him easily, without pulling any guards. He respawns within 5 seconds so you can easily kill him again and again, to build up a giant aldor corpse pile! Guaranteed to get a big audience and a lot of /lols.
Now, here comes the extra fun part! If you're a priest, you can throw mind control on him... And on your pet bar you will get "Banish from Shattrath"!!!
It's easy to pull around the mob all over at the Aldor base, just by MCing him, running out of range, MCing again and so on. Then you can banish everything that's hostile (guards, other elite npcs). They usually pop back pretty fast but it's still darn funny.
Here's a pic of me banishing a guard:
You can also MC the elite called "Adyen the Lightwarden" to get some paladin skills such as hammer of justice, divine shield (beware, if you pop it, MC breaks), holy light and crusader strike. You can also MC the "boss" of the Aldor, don't remember what she's called, to get some priest skills. But Kaan is funnier since he has banish. You can also MC the guards for banish, but that's a lot dumber because as soon as MC breaks, they will banish you. Kaan wont.
I'm also currently trying to pull Kaan out from the Aldor's Rise. It's not possible to take the lift, so I'm trying to take him down the hills. If you just keep spamming MC he wont reset, but when he jumps down the hills he might reset.
Hope this isn't a repost, it's at least very very funny to do as a priest.
