I'm going to have to ask you to prove your math on this one. On a per-point basis, haste scales faster than crit for giving percentages, i.e., it takes less haste rating to get 1% haste than it takes crit rating to get 1% crit. 1% haste increases the damage (over a sufficiently large amount of time) by 1% for anything affected by haste. In this case, in the time you would get 100 ticks of Censure, you would get 101 ticks. 1% crit also increases damage by 1% (Censure crits for double I believe, but I'm not actually certain), as 100 ticks would produce 101 ticks worth of damage. Of course, subject to RNG. Less haste rating gives 1% haste compared to crit rating for 1% crit. Censure crits don't proc anything. Therefore, haste has risen in value compared to crit. No, its value is not likely to have completely sky rocketed. After all, censure still benefits from crit, just slower. Also, the relative value of mastery compared to haste and crit has dropped. Again, not by jaw dropping amounts.crit and haste affect dots at the same rate
If you're on the fence between crit/haste, just one more reason to choose haste. If you're firmly in the belief that crit is better than haste, the change in relative value is probably small enough to not rock your boat. If you believe haste is better than crit, well, doesn't affect you since you're already stacking the stat that benefits the most from the hotfix.
