This is my guide for the raiding rogue, or those aspiring to be one. It covers everything you'd need to know about specs, gearing, and the dps itself. Hope you find this useful. Feel free to suggest things to add or ask questions. Enjoy.

My sources will be from various people and posts at Elitist Jerks, WoWWiki, and WoW Forums. Pretty much in that order of importance.

SnD - Slice and Dice

Cycle - The order in which you use up your combo points. Often, notation will look like 1s/5r or 5s/5r basically Xs/Yr. What that denotes is to use finisher "s" after X amount of combo points, then finisher "r" after Y amount of combo points, then repeat. In our cases, "s" will be Slice and Dice, "r" will be Rupture, "e" will be Eviserate. Also, an additional notation sometimes is "Xs/Yr cut". What "cut" means is to start the cycle again immediately refreshing SnD even if there is a lot of time left on it. Those type of cycles tend to tell you that your energy will start to cap before SnD wears off and it's not worth using other finishers, so it's better to just refresh SnD beforehand.

Energy Capping - Energy comes at 20 sec per tick (normally) regardless of what you do and caps at 100 (normally). When energy is capped out at 100, additional energy ticks do nothing and are thus wasted.
