Patch 2.4 not only brought us a new island, but also a new great spot for the most annoying ganking. Im not talking about Sunwell Isle, but Blade Edge Mountains.
If your realm has reached phase 2, you will be able to make this quest: Intercepting the Mana Cells - Quests - World of Warcraft
The area is this one (the points @ Raven's Wood is wrong): Smuggled Mana Cell - Objects - World of Warcraft
Why its a good place? You need a random drop off those mobs, which when used makes you enter another dimention. If killed while doing the quest, you not only have to run back, you will also have to get a new item to enter the dimention again.
Which i would say is a pain in the ass
Another good spot is the Throne of Kil'Jaeden when people are doing this quest: Blast the Gateway - Quests - World of Warcraft
By killing them while they are doing the quest, they will have to start all over againDamn ive pissed off alot of alliance!
