Re: joining servers that haven't updated yet --
I haven't been able to do it. Getting a lot of 'expected version 7, got version 6' errors. Have only been able to play some bot matches so far.
It's good. It's really good, seemingly. Good enough that said bot matches were actually satisfying (!).
The lightsaber swinging seems to be more predictable now -- e.g., attacking w/o moving actually does consistantly produce the top-down slash in all stances. So that's nice.
They also restored/updated a lot of animation to the swings. That may or may not be a good thing (read: does it affect latency at all?).
Has anyone else noticed the game running a little slower since patching?
And hey -- new maps! Good ones, too. The hangar bay with reflective floors is really cool, and you get the ROTJ final duel music in the 'Ceremonial Hall' level.
