These macros are ideal for the a shadow priest, though several of them could also be used with a more traditional holy or discipline talent spec.

I saw this posted on a few other WoW sites a few weeks ago, and never really checked it out, but I have to say now that I have I'm impressed. Essentially, there are graphical options available via console macros and scripts that are not visible in your normal user interface.

Using the macro below you can dramatically increase the amount of vegetation you see on the ground, the distance at which objects draw on your screen, improve clarity and sharpness of objects, and get crisper weather effects.

/console groundEffectDensity 256
/console groundEffectDist 200
/console detailDoodadAlpha 100
/console horizonfarclip 2112
/console farclip 999
/console characterAmbient

Note: You need to create a new macro and click it once for these changes to take effect.

Before

Warriors are easily one of the most versatile classes in the game. Whether it is PvP or PvE they will always be needed and used. In PvP, being able to limit the damage a rogue is doing to your partners or even greatly increasing your own survivability can allow you to win. There are simply too many abilities for any warrior to keep track of, and macros are a very efficient way to solve this problem. Every top warrior in arena uses macros to better their skills and utility.

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.
Combat

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.
