Hi, I've spent a lot of time looking, and I finally found something which wasn't a repost, and wasn't useless! So I decided to share it with you. Please, if you find it to be useless feel free to report me, but I'm pretty sure it isn't. Not amazing, but it is helpful.
In Halls of Origination, inside the elemental room sorta place, there are 4 elemental wardens. The Earth Warden (Earth Warden - NPC - World of Warcraft) has two abilities. Impale and Rockwave. Both are unavoidable, except Rockwave can be tricked into hitting the tank.
By taunting in the last 1/6 of the cast (may be more or less, narrowed it down to here), you can force the Rockwave to go after the tank. The reason you'd want to do this is simple. Rockwave is physical damage. And AOE. Nobody should be standing in front of the boss, as it is usually tanked towards the back wall. Tanks usually have much better mitigation than clothies, healers, and even plate DPS, due to talents, shields, and anything else of the sort. It's also a vengeance boost. So not only will it only hit one person, it will hit the person that will take the least damage from it! This takes very little practice to perfect, and you'll be able to taunt every one onto you with ease, making the fight a tank and spank for tanks and DPS, and fairly simple for healers.
Thanks for reading, and I hope you find this useful!
In addition, I've found this possible on another boss, making me think it works for many. The dragon boss in VP can be forced to do it as well, but you have to be a LOT more specific. And in this case, there is no real reason for it, as druids are the only tank with additional magic resistance. It's still useful to know. And good to practice on! It just takes a very good reaction time and a ton of practice. Good luck!
