It says updated the 14th but parts of it were actually added yesterday as far as I know.
Such as..
Set Bonuses
* The PvE hunter 4-piece set bonus has been redesigned. It now reduces the cast time of Steady Shot and Cobra Shot by .2 seconds.
* The PvE warlock 4-piece set bonus (Fel Spark) now increases the damage done by the next 2 Fel Flame spells by 300%, rather than increasing the critical effect chance of one by 100%.
* All PvP 4-piece bonuses have had their flat stat values cut in half. Primary stats are very powerful in Cataclysm, so much so that players were considering using PvP gear in PvE just because of these primary stat bonuses.
* The PvP priest 4-piece set bonus has been redesigned. When Power Word: Shield is cast on the priest, movement speed reduction effects are temporally suppressed for 4 seconds.
* The PvP warlock 4-piece set bonus has been redesigned. It now reduces the cooldown of Death Coil by 30 seconds.
* The PvP warrior 4-piece set bonus has been redesigned. It now reduces disarm duration by 60% (does not stack with any Weapon Chains).

I, on the other hand, prefer a command-line system 'cause i'm so hardcore
/north /north *You encounter an [Avatar of the god Set]!*
/cast sheild *sheild spell unavailable*
/csat shield *csat: unknown command*
*[Avatar of Set] beheads [Peasant]*
