It's a sad day when people who are corrected for being wrong start slinging insults. But, since you seem to want to address specific things I'll bite.

First off, your example IS a 7.5 second window. Why are you trying to say that 2.5 ► 10.0s is the new topic? Because it's not.
Second, regarding the 0.825 potency difference, that's only assuming one of the available ticks proc BL. Whereas the rotation I mentioned does not rely on that, and still out performs it even if it does, even if it is by a fractional margin.
Thirdly, obviously you have some insecurities if you're insulting me when you're wrong. Notice how when I was, I admitted as much and even agreed.

What I suggest you do, is go do some parser testing in Coerthas. Because talking hypothetical scenarios seems to be something you don't do very well.

As far as your last sentence, if you don't have anything constructive or correct to say, usually it's best not to say anything at all.

Cheers.
