So, I get to 83.63% Mastery but instead have NT ticking 15 times per GCD.
177.63*16 = 2842.08
183.63*15 = 2754.45
So even 1800 Mastery isn't enough to warrant it. The thing is, the more haste you sacrifice, the more potential breakpoints you're losing. Haste breakpoints are almost always worth getting if you're not stretching to get there.
