I'd thought I'd make this guide just for fun. I'm not saying rogues who read this will have to encase themselves around the following strategies, these are simply the ones I use when dueling one. Anyways right now it can be hard to kill warriors one on one in a duel. This level of difficulty and strategy and change drastically upon spec, so I've broken it down to 4 possible specs rogues may be using today.

Disclaimer: Playing as a Mage in 2v2 is viable and will get you your desired rating of 1850 or 2000. However, it should be something you do for fun--you will save yourself alot of stress this way. Just remember, for every mage above 2k there are about 30+ druids.

That being said, I wanted to make my first Mage arena guide something very basic.
