Improved Flamestrike (mage talent)

Improved Flamestrike reduces the casting time of Flamestrike, making it an instant cast spell with both ranks. Also causes Blast Wave to automatically cast Flamestrike if the Blast Wave hits 2 or more targets, saving the global cooldown. This gives Fire mages a lot more AoE damage potential, since they have 2 instant AoE damage spells that can be easily linked together. The daze from Blast Wave will also keep targets in the aftereffect damage of Flamestrike longer. This has uses for both PvP and PvE.
