So, shortly after I pre-ordered the game, a friend of mine on Facebook was kind enough to give me a beta key to get me started. My initial thoughts on the beta were that it was what I expected it to be from frame rate drops regardless of latency to some really cool moments. And given that this is a beta and all, I thought I'd chillax a bit and just play around. 5 Placement matches later, I was part of the Bronze League (whoop de doo) due to me having way too much trouble taking down the Protoss given that most of them are either way too aggressive or I just didn't scout accordingly.
Still given that this is still a beta and all, I have plenty to time to understand this expansion's metagame.
