I am sure that I will enjoy running through the new Zul Gurub and learning the few new mechanics. I'll likely enjoy running through Zul Aman again as well. I assume it will feel similar to VC and SFK, with a few "whoa, that's cool, look at that!" moments thrown in for good measure.
But after that, the love affair quickly dies.
The truth of the matter is, I've been tanking, raiding, and leading groups for over half a decade. When I close my eyes, I can quite literally picture every single pull from ZG and which corners can be closely cut around huts to avoid mobs. I can, without a doubt, remember the exact path to take from Jan'Alai to Halazzi. No matter how retooled the content is, nothing will take away the feeling that I have done this before, and done it many, many times before.
SFK and VC were the same way. They provided a few, fun, nostalgic surprises, but when it comes down to it, I take the same lefts and rights that I've taken since my first character oh so many years ago.
This is a new expansion. The world as we knew it changed forever. I happily followed you down this dark, experimental road. Why then, after getting used to nothing ever being the same, am I yet again being fed the same content that we were asked to leave behind.
