Ok have fun having mediocre dps. The science you speak about is some random post from last year with low gear and made by someone that din't really give any good info.
The diference is even bigger in the new coil because either you have huge up times like t8, or you have small up times like t9 and you have to do all the damage you can before the boss jumps.

Besides you are trying to tell people with real high end experience that know what they are doing how to play their job when you haven't even finished t6.
