Oh, this is the Krippa guy?
I agree with him on the NDA issue. However, it seems GW2 will be the only game that handled server congestion pretty well (Overflow servers). As for everyone else, it will always be a problem in Open Beta.
Reading the comments I thought he was going to blast the game hard going into this, but he didn't. He said Error 3102 and the Server lockout caused him to not play with his friends, which is a valid concern going into Launch. I already know some people like PandaRei who had to switch servers because her friends couldn't get into Hyperion.
So yes, it is a valid concern.
