The patch probably comes to us after next week's maintenance (it's posted on the european wow website that it'll get to them at next friday's maintenance, so no reason why we should get it later than them unless they're treating europe as test servers

)
Anyway on the PvP honor system... Currently the only dishonorable kills are from those 'civilian' types of NPCs. Everyone else is fair kill. Blizzard is impleteing the HONOR system, so they do not plan to DISHONOR anyone even if it's in the case of 5v1 ganking. So try to travel in groups from now on

It's just realistic... I mean in a hostile environment, would u travel alone?
Ganking will continue, but the consequences have altered. The ganked (lower level ones) have a chance now to gain honor, while the gankers (higher level ones) will have nothing to gain. For example, a level 60 have NBTD and go to Booty Bay to gank those level 40 people. He gains no honor obviously because of the level difference. But then, somehow the level 40s grouped up together and killed the level 60. They however, gained honor...

Also if you read thru the preview, it's mentioned there that your ranking will deteriorate if you do not keep up on your PvP action and kills. And the rewards you gained can only be used if you are of that PvP rank... I wonder how will that work out... I mean let's say I'm on holidays now, so I get to participate in lots of PvP action. I managed to buy the epic PvP mount. Now, holidays over, so I participated less in PvP. My ranking dropped. Now I can no longer use the epic mount I bought earlier... WTF?
