Okay its taken me 3 years of being a complete scrub to muster this shitty guide up so here goes!
What you need:
2 x WoW WOTLK Accounts.
1 x Some form of AOE Class level 80 with the RAF 2 seater rocket mount
1 x Lowbie charcter with WOTLK enabled. (My character was lvl 56 at the time of testing this)
1 x Brain that does not bore easily.
Guide:
1. Take both your chars to Dalaran and set up a group. (I got a portal from a mage on my lowbie)
2. Get your main character and have him mount on his 2 seater RAF rocket mount and get your lowbie alt to jump on with him.
3. Fly to Icecrown in the displayed on the location below dropping off the lowbie character on the rocks so he is safe from pulling. (trust me he will pull if he is on the ground)
4. Pull the large packs of mobs (Converted Heros) using your lvl 80 moving in a 9 to 3 o'clock zone so once you reach the end the mobs that you pulled at the start shall have re-spawned.
5. Keep doing this until your brain is fryed. (Make sure you stay in range of your lowbie char otherwise no xp)
More Details:
What makes this rather good from any other location is that i am getting around 280-300 xp per mob killed on my lowbie (Lvl 56)
Are accounts where not linked so if you want to do it with your buddy that are both linked it could be 900xp!
However cannot confirm this as i dont have linked account atm but just keep it in mind.
Now when you consider each pack you are pulling in this location usually come in 10 that's 9k xp for what a 30 second pull?
Looting these mobs can also carry a benefit from the silver and cloth they drop, so not only are you gaining xp for you lowbie you also gain some pocket change
This was done using a Prot pala to pull.
Think this is the first guide i have ever wrote in my life so please be easy.
Images will be added soon along with a bit more information hopefully the guide above in its current state is enough for you guys/girls a fairly decent idea what the hell am talking about.
Please feel free to add tips about other location or anything better than my current post!
Thanks!
