This is very similar to the build I've been running on Kerrigan before I started looking to see what builds people have been running. The only difference is I often take Ultralisk to help push/scare people off - which doesn't always work when you're doing versus now that the game has been running alpha/beta for a while and there are a lot more people playing now. I was starting to wonder if I was insane running marksman since I didn't seem to see many people running it and then I saw this...
