So he can't be talking about Thrash-less rotation (which was not optimal BTW, as optimal was back the low-thrash rotation which would occasionally have a Thrash in place of Saber Strike) ...
This is all a moot point since 2.0 reduced the force cost of shock and thrash and you are correct that every rotation used at least some melee attacks, but for accuracy's sake:
Actually, KeyboardNinja proved that the Thrashless rotation was superior because it minimized the time between Force Lightnings w/ 3x Harnessed Darkness. ("Actually, it looks like the optimum is no Double Strike/Thrash at all, if the goal is to achieve TkT as frequently as possible." http://www.swtor.com/community/showp...2&postcount=12
So, a big jawagram 'nice try' to you for flexing your nerd muscles.
