I've been pretty vocal about what I'm not looking forward to in MoP, but believe or not there are some things I am looking forward to. Blazing Speed and Grimoire of Supremacy are two of these. The new pets for the former have as of yet, unannounced new, stronger abilities. I've given these some thought as to what I think they should be, and thought I'd throw those ideas out there, the idea behind some of these is clearly to offer utility a raid group might otherwise lack in a similar manner to BM Hunters, while trying to be a logical extention of present abilities:
Fel Imp:
Singe Magic -> Cauterizing Flames: Removes all magical effects from the target, and heals for 5% of their health over 5 seconds, while preventing the application of magical effects.
Void Lord:
Sacrifice -> Void Shield: Summons a shield over an area, reducing damage taken by friendly units by 25%.
Consume Shadows -> Paranoia (Passive Aura): Greatly increases stealth detection to all nearby friendly targets within 30 yards.
Shivan:
Seduction -> Skewer: Skewers the target stunning them. In addition Skewer inflicts X damage every 2 sec.
Whiplash -> Spinning Pain Spike: Leaps towards an enemy, grabbing them and inflicting significant Physical damage.
Observer:
Devour Magic -> Consume Magic: Dispels magic in a 15 yard radius, removing 1 harmful spells from each friendly target and 1 beneficial spells from each enemy target. Affects a maximum of 10 friendly targets and 10 enemy targets. This dispel is potent enough to remove Magic effects that are normally undispellable.
Wrathguard:
Pursuit -> Intercept: Charge an enemy, causing X damage and stunning it for 1 sec.
Gains: Bloodlust.
The Guardians obviously can't have controlled abilities, so I presume they'll just receive more powerful versions of the current spells. That said, I'd rather receive them on a separate talent in place of Sacrifice, but that's been another thread I made on the EU forums and had a mixed reception.
