- Bloodlust/Heroism will, again, stack with Icy Veins.
- Bloodlust/Heroism will not stack with [the new] Power Infusion, however.
For those that don't know about Shamans, Bloodlust and Heroism are Shaman abilities (Bloodlust is the name of the spell for the Horde, Heroism is the name of the spell for the Alliance) that decrease casting time by 30% for 40 seconds. It is often used in raids to get that extra "umpf" necessary to get a boss down quickly.
Icy Veins is a Mage talent based spell that decreases casting time by 20% for 20 seconds (and increase the chance the target will freeze by 20%). The combination of Bloodlust/Heroism and Icy Veins is a very potent combination.
Power Infusion is a Priest talent that will have some changes come patch 2.4. It will now decrease casting time by 20% as well as decrease the mana cost by 20%. It's interesting that Blizzard decided to allow the stacking with Mages, but not with priests. The difference in the two spells is that Power Infusion can be cast on other targets, while Icy Veins can only be cast on yourself. Indeed, this follows with what Tharfor said in his post (which Drysc left out).
What do you think of these changes? Any major issue with them?
