EPT1. Hellion's do damage immediately but their animation time is for a half a second longer.. this is significant when microing against z-lots or zerglings.
2. Workers will automatically mine vespene gas when right clicked on a refinery that is building after it's finished.. they will not however auto mine from a refinery if the cc rallies them there before the building is finished.
3. Rally points can be made such that units can take turns.. this is useful when you want a unit to spawn on a particular side/part of the building that is not along the path of their ultimate destination.
4.) Spamming right click with a group of flying units then hitting patrol in one spot causes them to stay stacked... I only mention this because it may play some role in the way microing flying units evolves in sc2
Thanks for your contributions.
