Every week, WoW Insider brings you Encrypted Text for assassination, combat and subtlety rogues. Chase Christian will be your guide to the world of shadows every Wednesday. Feel free to email me with any questions or article suggestions you'd like to see covered here.
Tricks of the Trade is a strange ability for rogues. Why would we sacrifice our own damage (by spending energy) to boost the damage of someone else? Aldriana and Pathal have both spoken out against TotT's misguided benevolence and its boring mechanics. Rather than being a situationally-useful ability that we pull out when the time is right, TotT has become a set-and-forget chore that we just auto-cast on the second-highest DPS in raid.
Lore issues aside, Tricks of the Trade is a pretty good ability. Used properly, it can greatly accelerate the rate that tanks pick up aggro, which makes dungeons and raids just a bit easier. While it's a DPS loss for the rogue casting TotT, it's a net gain for the raid's DPS, and that's a sacrifice that we'll have to make. It's also incredibly potent in PvP; granting an ally a 15% damage boost is a pretty big deal.
