good macro for the win. i saw an article on team liquid i think about a guy you literally never micros and just wins out macroing people to masters. not hard. get early expo, build some units, dont die to cheese or air, get 3rd, death ball with maxed unit army and upgrades.
I just played a few games without rallies for either drones or units. Although I suppose it wasn't within the exact limits of karak's lines. I did std overlord scouting and sometimes put out a scouting ling, and as usual just hotkeyed my hatches only. Playing with no rallies was somewhat challenging...it's a lot harder to get the "swarm" going without being able to funnel reinforcements directly into the battle. I did get a little more comfortable with it as I progressed. Something I noticed throughout all my games was that I stopped droning wayyy earlier than I normally would. Not sure why. Anyway, went 3-1.
there were rally points in BW, but they didn't cause workers to start mining, so you'd put the rally point right next to the minerals and have to manually select each worker to tell it to start mining.
