One constant, no matter how hard I've tried to ignore it, that has always existed in WoW is that one spec is always "best." The class designers are constantly tweaking the numbers and trying to keep things balanced, but once we all sit down with our collective calculator and spreadsheet, one spec always emerges to rule them all.
It has been a sad reality that while we have always had freedom to choose a spec and personalize it to fit our preferences, when it comes time to raid at high levels or take part in PvP at high levels, that freedom essentially vanishes. You can make arguments for utility over damage or for certain specs in certain fights, but in most cases, under most circumstances, you're going with whatever cookie-cutter spec the internet has agreed upon that week, or you're not getting an invite.
Well, now we have a fresh expansion to leverage our calculators and spreadsheets upon. It's still early in the beta process, and hard numbers are in short supply. Still, the overall design of the specs seems to be fairly well-defined, even if the actual percentage points are still in flux. What conclusions can we draw at this stage? Which spec looks to put out the best damage? And most importantly, which spec will let us kill warlocks most efficiently?
