I really liked the hunter. I'm not sure I liked the hunter enough to get that mage, though. He got himself killed a *lot* and barely out-damaged Skree. Even he went single-target for those 1-2 attempts, he failed to out-DPS the OT. Plus we already have a mage. Diversity (cross-buffing) is strength, and we have an option in Atal (and hopefully Xelian!) so we're not stuck with him.
I'd say keep the door open if they come as a package- the amge might improve and we don't want to be left in a lurch spamming trade. Atal might not be ready next week and we might fail to convince Xelian to stay on WoW the week after. But keep searching.
