So many years ago, I picked up a copy of World of Warcraft. It was my first MMO, although I had played my fair share of RPGs. Once I started my rogue, I found myself leaning on Sinister Strike to kill everything. Eviscerate didn't seem very potent, and Slice and Dice was just some dumb buff. Other games had taught me that damage now was better than damage later, and so I focused on simply hitting my targets with Sinister Strike as often as I could. Stealth only slowed me down, and so I would just run up to my enemies. The learning curve of WoW isn't exactly steep, and so I was able to level pretty easily even though I was playing poorly.
Looking over our talent trees today, it's clear that Blizzard has spent quite some time refining the rotation of each build. In the past, we relied on diligent theorycrafters to guide our every move. Now, the talents themselves tell us how to play. How can you read Master Poisoner's tooltip and not realize you should be using Envenom? Improved Sinister Strike clearly points combat towards Sinister Strike, while Energetic Recovery makes Recuperate a staple of the subtlety builds. As I've mentioned before, each spec really has its own combo point generator and finisher priority. Figuring out what abilities go with which spec isn't rocket science; it's merely common sense.
