If losing 1 haste means losing 1 nuke during peak, the "lost" nuke will still land at over 99% of peak. That change is trivial compared to 5.x where 1 haste at a breakpoint adds a full DoT tick per cast.
I'm not saying haste can't be valuable. I'm saying that you will be hard-pressed to find a point where 1 haste is a 1% DPS boost to your rotation. Something similar to that is what we mean by a Haste breakpoint in 5.x.
