Right - so according to Simcraft I dropped to 54k HPS (after Wednesday) from 90k HPS (currently with no hotfix), this coincides with an increase in DTPS from 9 to 15k - the increase in damage taken is quite significant, however it seems that everything will still be playable - I do not think this puts us on the DK level
The 703-03 version of simcraft however also puts out the following stat weights (for 25% vers, 4,6% haste and 34% mastery):
Haste 8.41
Crit 7.20
Vers 3.04
Mastery 2.42
STR 1.00
Apparently I did something incorrectly since this cannot be right...
