Okay, combining Nail's and Mablak's posts to answer: yes, the problem for me is that SD moment is unpredictable. Such a dramatic change of game situation can't be random. I may agree with the fact that it may spawn some interesting strategies and such. But, I guess you know about another aspect of this, pretty ugly one, the thing called "waiting for SD". Some players build the whole game in the way that they just jerk around, doing nothing special and wasting their time on purpose, and this really pisses me off sometimes.
