Hey, this game looks unique and fun, and I'm considering preordering it now and giving the beta a try.  I have a few questions that I thought I would ask around here first though.  First of all, I realize that it's a very early beta, so what all of you have is far from what the completed game will be like, but what is your impression of the game?  How would you describe the gameplay to someone who does not play Defense of the Ancients?

My second question is regarding Impulse.  Can you play this game without using Impulse?  I have nothing against Impulse, it sounds good, but I would prefer to have everything on Steam just for the sake of consolidation.  If the game is Impulse only, do you need to actually have Impulse running to play multiplayer, or is that only necessary for updates?

Thanks in advance!
