Yes it's good that they fixed that bug in this patch. And that they are patching to get the bugs out. But like others in the beta, this game needs almost another 6 months of testing. Just to fix the current bugs/skills/content. Sadly we are seeing this more and more in MMO games.
Also they seem to say it's very scaleable... but my low end system couldn't even run the game over the course of the beta. (1200mhz, 758 megs of ram, geforce2mx 64megs and a geforce 3 card) Although I didn't try it out on this system for the last few patches, I know i've heard a lot of people with close to same specs saying they had big problems running it.
