living bomb spam in wintergrasp, here i come.
Mages
* Arcane Blast: Mana cost reduced by 12%.
* Frost Bolt, Cone of Cold, Frost Ward, Ice Armor, Frost Armor, Frost Nova, Ice Lance, and Ice Barrier: The mana cost on these spells has been reduced by approximately 15%.
* Invisibility: Can no longer be interrupted by a hostile action or damage done during the 3-second Fade time, however an invisible mage is still vulnerable to Stun and Silence effects.
* Mirror Image: Images will no longer trigger the death sound when their time expires.
* Talents
o Fire
+ Empowered Fire: In addition to its existing effects, this talent now also grants a 33/67/100% chance to regain 2% of base mana each time the Ignite talent deals damage.
o Frost
+ Empowered Frostbolt: Instead of increasing critical strike chance by 2/4%, this talent now reduces the cast time of Frostbolt by 0.1/0.2 seconds.
+ Permafrost: In addition to its existing effects, this talent now also causes the mage's Chill effects to reduce healing received by the victim by 7/13/20%.
And these are the bugfixes:
Mages
* Arcane Instability: Tooltip reworded to clarify design intent.
* Burning Determination: Some Silence and Interrupt effects that did not trigger this talent will now trigger it properly, including Shield of the Templar, Garrote and Gag Order.
* Combustion: Fire spell misses will no longer trigger this talent.
* Conjure Refreshment: Rank 1 food will no longer overwrite the drink buff from rank 2 food.
* Fireball: Periodic damage from this spell can no longer trigger Combustion.
* Living Bomb: Periodic critical strikes from this ability can now trigger Ignite and Hot Streak.
* Mirror Image: The mirror images will no longer complete casts of Frostbolt on targets which are Polymorphed at the time their Frostbolt channel finishes.
* Molten Armor: Critical strikes from the effect on this armor will no longer trigger Ignite.
From the US patchnotes.
It looks like the living bomb change didn't went live, well ticks can proc hot streak though. I presume hotstreak ticks and multiple targets would make it a pyro spam fest.
