reply to Pallan You don't say which spec your 2 priests play so this may not be an issue but you really don't want 2 Disc healers in one 10 person raid. They will be fighting over who gets to shield people because there's a debuff after your shield gets used up so you can't get shielded again for a while. Just not a helpful dynamic both for focusing on effective healing, and getting along with your raid group.
Our hunter has to use his spore bat all the time and he hates looking at it. He actually named it "Damnsporebat."
I just tamed one this past week to help out our casters when we're missing the buff. I named mine "RogueRipper". Attack speed is my primary concern. If no one else brings that, I've got my Hyena out...screw the other casters!
