With all the RPPM trinkets in this tier your best and worst pulls are going to depend a lot more on how lucky you get with trinket procs than how lucky you get with crits.
I actually took some haste reforging myself yesterday but only to a point of slightly a bit more than crit so rune procs were haste not crit (9014 haste, 9011 crit, 762 mastery) with this gear and went MM on few fights. Quite compareable with SV on ST patchwerk like primordius burn strat.
As for SV I would rather go still with crit being not overhauled by haste but with closer numbers (crit=>haste).
Check ask mr robot. If it says less haste it is probably right, they are usually solid with their maths.
