Atleast it's better then Age of Conan and how that went. Their PvP Beta Weekend was a complete bug fest that was really screwed up (people could actuall walk through a wall and be under the map shotting other players with spells and bows). What really blows out the ass about it was that they kept bragging about PvP XP and levels, and it was even in that PvP weekend, but it was NOT IN LAUNCH (nor has it been in yet, and it's been pushed back again and slated for the Sep 10th patch at the earliest).

But, Age of Conan somehow got a mircle patch between Closed Beta and Open Beta/Release because the game was way more stable....and that was only temporary as every other pach Funcom released after that broke the client more and made stability a joke.

The Preview Weekend for WARhammer was excellent, and I only came across two problems the entire time: 1) Wasn't able to log into my Greenskin characters for a bit of time (not sure what it was about, only two hours, but I could create and log-in to a Dark Elve just fine in the mean time on the same server)...maybe it was over population of the Greenskins, IDK and 2) Client closed out on me...not a crash, or a freeze, it just closed (I had this happen to me twice on TF2, I think it's in association with this shitty Vista).
