Got my beta invite
Downloaded the client yesterday, played my first match this morning, crushed some unfortunate soul with the protoss carriers. Graphics are on ultra with my system, and they look nice and purty. One nice touch that I love is the waypoint setting system they use, when the unit is selected it shows move points in green, with green lines connecting them, and the attack points in red, with red lines connecting them. Doesn't sound too impressive as I type it, but it looks great. Also, the air units have a thin green line connecting them straight down so that you can see where exactly they are relative to the ground. Again, looks a lot spiffier than it sounds.
Battle.net as a whole looks great, too. Going to be doing pretty bad on my next round of midterms methinks.
