When we last left our devious, poison-festooned heroes, they were assassinating the heck out of every raid boss in sight, much as they have been this entire expansion. Assassination has been the spec of choice for raiders of all stripes in Mists -- but might Patch 5.4 change the balance?
The answer may depend as much on you as on the gifts that WoW's designers wrapped up and handed us for the new patch. Combat and subtlety both are looking like perfectly good options in almost every situation. Unless you're with a group that is seriously trying to squeeze every last drop of damage out of its DPSers, and you're already playing your spec perfectly, your main criteria for which spec to use should rely on 1) whether you enjoy it and 2) whether you've got the right gear for it.
