Many wow gold people say that combat is best for leveling.
Night elves have higher agility and shadow meld ability while in combat or out; a move that works similar to stealth but doesn't allow you to move about. Humans have increased expertise with many of the weapons and the ability to remove all fear, stun, mind control, traps, slowing and the like. If you're planning on going Horde, Troll Rogues have increased critical strike chance in a few ranged weapons and higher agility as well. They can increase their attack speed on a low cool-down. Undead Rogues can become completely immune to all fear and charm effects for about 15 seconds, which is great for going up against Warlocks; making them almost completely useless against you. Blood elves are up for debate about Rogues, but their ability to silence everything in a radius is nice for both Player vs. Player and Player vs. Environment.For our part, leveling in the spec suits you best is what is going to allow you to do the most efficient leveling. Many wow gold people say that combat is best for leveling but there are other specs that allow you to do quite significant damage. Assassination has some awesome crits for leveling and sub will allow you to quest much more efficiently and avoid mobs that you would have to take down if you were a different spec. If you go sub or assassination, you can also quite easily Player vs. Player whenever you feel like it.When it comes to gearing, it's pretty important for Rogue.
