So the MoP beta raid testing starts tomorrow. In light of the disaster that was DS, the general disappointment that was Cata and with the large size of the beta, the confluence of those factors could really be a make or break kind of event for MoP.
Yes it's still early and yes it's just a beta but first impressions die hard and if the raids don't present some kick ass potential from the first look there's going to be some tough days ahead for the WoW team. The raids don't have to polished at this point, they just have to be interesting and engaging enough for the raiding community to say "yeah, they're back on track after DS, this is going to be fun, engaging and challenging to clear."
If it's a re-skined, recycled mechanics type of place, then forget about it.
