In Ghostcrawler's Buff and Debuff Design post, he points out that all Warlocks will bring the Stamina buff.

"Stamina
Effect: +10% Stamina
Example: Power Word: Fortitude
Brought by: Any priest, any warlock, any warrior"
I'm curious as to if this really is the case, my group is currently trying to build a raid composition for Mists, but this seems to be the real limiting point. As it is right now, our composition looks like this (note that the hunter does bring spell haste, the calculator simply has not been updated):

Have all pets been standardized (similar to hunters) to perform equally, or will our warlock be pigeon holed into playing only one spec? It seems odd to me that most buffs have become standard across all "dps" specs of a class (exceptions being shaman and druid because their specs fill different roles), but this one might not have. We would prefer to bring something like a mage in our group, especially from a token standpoint - we already have 3 on the conqueror token, but will hesitantly bring a shadow priest if we are forced into it.
