is there a way to add some aoe 2 the mage cc?
AoE:
Use Hot Streak whenever possible
Recast Living Bomb after every explosion (??)
use Flame Orb whenever possible
spam your filler nuke in between -- Filler nuke can be Scorch, Fireball, or Frostfire Bolt.
Notes:
Fireball is the highest dps.
Scorch is used during periods of movement or knockbacks.
Frostfire Bolt is an alternative to Fireball, but is lower DPS.
Make sure the Critical Mass debuff is always present on your target (Unless another Mage/Warlock is applying an equivalent buff).
After Patch 4.06 - there isn't much 'Mana Management' required to playing the Fire spec anymore.
However, make sure you have enough mana to cast Fireball during Molten Fury range (-35% Health), Boss weakened phases and during powerful trinket on-use or passive proc periods.
Recognise that "Ignite" is by far the *most important* contributor to a strong Combustion -- Don't use Combustion without Ignite present! Ideally, use Combustion when Ignite, Pyroblast (Dot), && Living Bomb are on your target.
The biggest Ignites will stem from Pyroblast and Fireball crits, resulting in bigger Combustions.
You can, however, fish for Ignites via Scorch if you have no time to wait - Download
CombustionHelper to assist you in managing this cooldown more easily.
Put Living Bomb on 3 targets, use Blastwave on cooldown and spam Flamestrike.
Mana efficiency:
Mana management is also an essential part of multi-target dps. You will not have enough mana to continually spam AoE for an extended period.
Fortunately, Fire specs have easy ways to dramatically improve efficiency. Use Blast Wave whenever possible as this is a very mana efficient spell. Even if you are in maximum efficiency mode, Blast Wave is still good. Only using Flamestrike only when its dot is expired will greatly increase its dpm.
You can further increase dpm by skipping Flamestrike and spamming Scorch with Living Bomb on a single target to fish for Impact procs. Impact procs are unreliable, but do MASSIVE AoE damage
