Well fuck, I totally forgot about the region lock. :/ Guess I'm the only one in the EU server in this thread. lol.Anyway, I completed the campaign and redid some missions on hard. I think I'll have to do another playthrough, though, for the merc/upgrade achievements. I also did some 3v3 with two buddies, we ended up in bronze league with like 2-3 or something. A good sign showing you're turtling too long is when you get attacked by 10+ battle cruisers.
I'm in the UK so I could only play on the EU servers too, but I emailed blizzard and they changed my key to a US one so I can play on the US servers.
