SE, Here's How You Make SSS Mean Something:

Then I raise you other point.

What is considered a 'perfect' rotation to you?

All jobs have an optimal single-target rotation, not sure what you're getting at.

Anyway, the idea is that you should have the option to enable an ilvl sync to see if you can meet the check with your rotation alone. I dunno why people are opposed to that. If anything it would make SSS a more accurate depiction of what a player needs to work on.
