I've been quite fond of the unified friends list on Steam. I was worried I'd miss that in Battle.net, since playing with friends is the way to go in StarCraft II. Turns out this game is so popular with my Steam and work circles that my Battle.net friends is always populated with some people to play with. 
 
I've been playing unranked placement matches for a while (usually 2v2 or 3v3) and it's been fun.  A friend and I recently got ranked and so we jumped into our division and tried some matches out. 
 
I tell you, losing 3 times in a row in one-sided blowouts is demoralizing. I was worried I'd hate playing 2v2. 
 
We got into our fourth match, and we had a strategy, but we built up for a while with very little noise. No early attack, no big signs of the enemy. Then, while scouting I saw the massive clump of Battlecruisers. I knew they were preparing to attack, but I decided I was not going to lose again. I just picked up my buildings and flew them away to my distant expansion.  I completely ignored the Battlecruiser attack, took 8 Thors, and went on a rampage through all of the enemy bases. That now-thinned squad of Battlecruisers eventually came back to attack my Thors, but they were dealt with, and the Victory screen popped up. Turning a near-certain loss into a victory in about 2 min was so sweet.
 
Okay StarCraft II. I get you. I'm in.
