The owner of this guide who goes by the name "NIKOLAAAa is no longer active, but guide is being preserved due to the quality of it.

This tutorial is for PVE players, and it's made for Cataclysm
I'll speak about Talents, Glyphs, Addons, UI etc.

Copy/paste from my application for guild.
At the moment Arcane is the gives the highest DMG output while not moving, and it'll also apply all raid members with a 3% DMG increased buff.That will improve the entire raids DPS by additional three percent, which is very good.

I'll start with Glyphs, so:
Prime:
Glyph of Arcane Blast
Increases the damage from your Arcane Blast buff by 3%.
Glyph of Arcane Missiles
Increases the critical strike chance of your Arcane Missiles spell by 5%.
Glyph of Mage Armor
Your Mage Armor regenerates 20% more mana.
Best choice for Prime Glyphs, it's based on your standard rotation and Increase damage/critical and mana regen.

Major:
Glyph of Evocation
Your Evocation ability also causes you to regain 40% of your health over its duration.
Glyph of Mana Shield
Reduces the cooldown of your Mana Shield by 2 sec.
Glyph of Arcane Power
While Arcane Power is active the global cooldown of your Blink, Mana Shield, and Mirror Image is reduced to zero.
Glyph of Mana Shield so you can easily stack Incanter's Absorption (Spelldmg) + AP without GCD.

Minor:
Glyph of Mirror Images
Your Mirror Images cast Arcane Blast or Fireball instead of Frostbolt depending on your primary talent tree.
Glyhp of Slow Fall
Your Slow Fall spell no longer requires a reagent.
Glyph of Arcane Brilliance
Reduces the mana cost of your Arcane Brilliance spell by 50%.
Slowfall is very usefull for Ragnaros fight, and Arcane Brilliance after combatress.



and now Talents, so far best build is 33/5/3

+ Improved Arcane Explosion
- Invocation

With this build you can help to AoE on few fights, but for fight like Halfus, Nefarian, Ascendant Council:
+ Invocation
- Improved Arcane Explosion
for some bonus damage :)


then macros =D

About stats priority.
Intellect>Hit>Mastery/Haste>Crit
You need 17% hit, but around 16-16.50% is enought.
Keep mastery +16, because with t11 you will get 10% reduce cast time and it will be easier to reforge.

Sockets:
Brilliant Inferno Ruby +40 Intellect
Artful Ember Topaz +20 Intellect and +20 Mastery Rating
If you got nice bonus boost feel free to use / or if you lack haste >
Veiled Demonseye +20 Intellect and +20 Hit Rating
Meta:
Burning Shadowspirit Diamond +54 Intellect and 3% Increased Critical Damage

Enchants:
Head: Arcanum of Hyjal
Use: Permanently adds 60 Intellect and 35 critical strike rating to a head slot item.
Shoulders: Greater Inscription of Charged Lodestone
Useermanently adds 50 Intellect and 25 haste rating to a shoulder slot item.
Enchant Cloak - Greater Intellect +50 Intellect
Enchant Chest - Peerless Stats +20 Stats
Enchant Bracer - Mighty Intellect +50 Intellect
Enchant Weapon - Power Torrent +500 Intellect
Helm in Off-Hand +40 Intellect
Enchant Gloves - Greater Mastery
Legs Powerful Enchanted Spellthread
Enchant Boots - Precision ili Mastery
Ring +40 Intellect
Some of those enchants are from last "retail" patch, but anyway see what do you need.

About professions Enchanting +80 intellect for ring, and Jewelcrafting are best.

Addons:

Bartender4 - ActionBar replacement mod.
NeedToKnow - displaying specific buffs, debuffs, i totems bartimer etc.
Quartz - model for casting bar addon
Scorchio2 - best mage armor, displaying everything!

My Warrior pvp alt =D but anyway, here you can see example of NeedToKnow addon



I'm kinda out of idea, but i'll write some basic Rotation and ask if you are interested about something.
Prepotion > Mirror Images > Arcane Blast x4 stacks (maximum stacks) > Arcane Power > Improved Mana Gem > Trinket (If you got on use) > Spam Arcane Blast untill 30% of your mane then evocation > Arcane Blast 4 stacks > Arcane Missle and HF. Most important part is to follow your procs (weapon/trinket etc) and then to spam more then x4 Arcane Blast for additional damage!
