I wasn’t terribly shocked by the Beta. I got mid 20s in very high from modest hardware. (i5 2400, GTX970, HDD), and found the combat to be usable after a little practice.
Sure there are a number of unfinished areas, sure there are problems that crop up with scripting and so on, but you report those that you find and enjoy the bits that work (which is lots in a fairly small slice).
I personally was happy to be able to try the beta, and have enjoyed bug hunting and general game play (hopefully more of the latter in the newer version out this week)…
I have been involved in the creation of complex game software in the past, and don’t see anything abnormal in the current (early) Beta state or the timescales and information that is being shared.
