I found this gem of a video that shows pretty much shows how complex and out of control Starcraft 2 really is.

As funny as it may be there is a sad truth to the video.
Too much work?
Here is an example that proves Starcraft 2 is as complicated as the above parody video. In order to make my tanks go into siege mode you have to do the following:
1, tab, z : enter siege mode
1, tab, x : exit siege mode
Why not just let me make a hotkey so I press a toggle siege mode button? ONE BUTTON. WHY DO I HAVE TO PRESS THREE KEYS JUST DO WHAT I WANT?
