I was 2v2 ATing with a friend when we got paird up with a lvl 1. I'm thinkin, oh good this should be easy. Bleh, one guy created massive towers around my base and the other made a million AOWs. It took forever to kill, 2 hours or something. That guys tree micro was impressive, but it was annoying.
Sometimes the best strategies are the ones newbies come up with.
