Introduction to Arcane:
Some fast things (For later use):
Arcane Missiles = AM
Arcane Barrage = Abarr
Arcane Blast = AB
Arcane Power = AP
Focus Magic = FM
Talent:
http://www.wowhead.com/?talent#of0Vs...xedcZbGc0o:Nzi
This is the baseline how your talent should look like, but you can make minor changes. Student of the Mind can also be interesting, thou it doesn't give too much plus damage for you.
Gear:
Ofcourse, the first thing to get is the hitcap.
You need 17% Hit overall.
-Precision +3% hit.
-Arcane Focus +3% hit.
-If you have an SP/Moonkin, that's another +3% hit.
-If you're playing the shi... I mean, alliance, the Draenei aura +1% hit.
So you need 11% unbuffed hit to be capped against a level 73 mob (without SP), which isn't really hard to obtain! I don't have a hit rating gem, nor a trinket and got 18% +hit even without the talents in ilvl264 gear, so it should be a piece of cake.
The stats you need always depend on your current gear, but the primary stats you need are, clearly, haste and spellpower!
Gems:
The meta socket (if you have one) should be Chatoic Skyflare Diamond.
That needs 2 blue gems, which should be: +spelldmg and +spirit.
The rest should be raw spell power or haste+spellpower for socket bonuses. Should be like HIT(to cap) > Haste > Spellpower > Crit > Spirit
Glyphs:
Since 3.0.9, you need the following ones for best results:
-Glyph of Arcane Missiles
-Glyph of Arcane Blast
-Glyph of Molten Armor
Since MB got buffed and now removes the mana cost of AM, Molten Armor is now a viable option for arcane mages.
Rotation:
It all depends on your support in the raid, the length of the fight and your mana pool.
The standard best damage rotation is:
¤Arcane Blast (x4)
¤Arcane Missiles (Abarr if you're currently moving)
Spamming AB until MB proccs is also an option, depends really on your mana. Also if you have T10 (4) setbonus you should wait for that MB.
Also, there is no "single" best damage rotation, it always depends on something, but you will learn that as you get some routine.
Let's say you're on a longer fight, you cannot afford this mana cost, it's easy to switch into a less mana effiency rotation.
¤Arcane Blast (x2)or(x3)
¤Arcane Missiles (Abarr if you're currently moving.)
Always remember, depending on your mana, if it's too low, you can always switch back to the 2-3stack AB rotation. This is the key concept in arcane. But mostly since the buff, you probably won't have mana issues, this was more likely to be a problem in Naxx25 days.
Macros:
Nuke Macro:
/use 13
/use 14
/cast Arcane Power
/cast Icy Veins
/cast Berserking (If you're a troll)
You can also write /cast Mirror Image in if you have the T10 (4) setbonus, but I wouldn't because it's on global CD and the rest is not. Starting with mirror image and shortly before global CD is over hit the Trinketnuke macro then immediately start casting should be the most efficient way.
You see? PoM shouldn't be in the macro, you should use that ability separately from AP, when these are on cooldown, or after AP expired.
This "nuke" macro is even more effective under Bloodlust, keep that in mind.
Fast Spellsteal macro:
#showtooltip Spellsteal
/stopcasting
/cast spellsteal
:::> Some other useful macros, thanks to iVaporized
Ice block Macro:
#showtooltip Ice Block
/stopcasting
/cancelaura Ice Block
/cast Ice Block
Invisibility Macro:
#showtooltip Invisibility
/stopcasting
/cancelaura Invisibility
/cast Invisibility
!!!!!!!!!!!!!!!!!!!
BUT, if you're a decent geared mage, you will see that if you pop all your CDs with bloodlust, you will go below global CD, and waste that precious haste, so examine your casttime, and if they pop BL you should only pop CDs which don't bring you under 1.0sec casttime on AB/AM(with MB).
This is the main reason haste doesn't worth as much as spellpower.
!!!!!!!!!!!!!!!!!!!!
Interesting things:
-At Malygos don't use your PoM, keep it until Vortex, where you can do the following for the best results and the least DPS lost due to the inability to cast: Abarr,PoM AB,Abarr,Fire Blast.
-You have the advantage of -40% threat, which makes this spec in most of the cases the best. You'll see other firemages struggling in aggro, loosing DPS with using invisibility, which you will mostly never have to. (Depends on the tanks and MD ofcourse!)
-You have a 2min Evocation CD, it's like that for a purpose, ALWAYS use it in time, it's your best friend.
-The T10 (2) and (4) setbonuses worth everything, if you see a ilvl264 hands or leggings better than the T10, don't switch them, these two setbonuses can give you shitloads of plus damage. (Like +18% with mirror image, combined with AP and other cds, I hit 30k AB-s)
-If you want to use Evocation and have the T10 (2) Setbonus, do it right after an AM, that will spare you time and shorten the time when EVO could be interrupted by incoming damage.
-Use an addon for watching Missile Barrage, I prefered SCT, but it broke so now I use Power Auras.
-Switch targets to another trashmob if your target dies before you finish your spellcasting. Also, don't use AM on a mob which is very near to death, because the missiles don't damage instantly after casting. (Marrowgar Bone Spikes are a great example)
-If your gear is good but your dps is low, the following problems could be happening:
-You pop your CDs at an inappropriate time.
-You take too much time to switch targets on a fight were are multiple mobs.
-You posision yourself on a bad place, eg. you stand on the other casters on Festergut and get the disorient.
-You move too much.
-Mental Handicap.
