You are both correct about the disparity. However, as far as that testing goes Auggidin, that would be more for a PvE situation. It would be better to do anywhere from 5-10 of these small pool tests seeing as it would be more correct in relativity to 19 WSG.
Did some math and here's what I came up with:
Wild Rider's Gloves:
Using this data from recount:
147 non-crit average.
295 crit average.
147 x 60.29 = 8862.63
295 x 39.71 = 11714.45
8862.63 + 11714.45 = 20,577.08
Gloves of the Fang:
151 non-crit average.
302 crit average.
151 x 61.24 = 9247.24
302 x 38.76 = 11705.52
9247.24 + 11705.52 = 20,952.76
That would be the damage for both for 100 ticks, in theory. For a larger number of ticks, like 600 ticks, just multiply the values I came up with by X/100, where 600 would be X.
