Uh...yeah. It was supposed to be DRK/SAM for BZ, I just made a typo. Hasso was still figured into the delay though. I would definitely agree that BZ isn't that impressive unless you happen to have Apoc. For the sake of completeness, I went ahead and figured RC vs BZ.
Code:
DpH(RC) * HpS(RC) = DpH(BZ) * HpS(BZ)
DpH(RC) * 1.92 = DpH(BZ) * 2.29
DpH(RC)/DpH(BZ) = 1.19~
You would only need to hit 1.19x harder with RC than BZ to overcome the difference in hits per second. This is also comparing BZ at its best to a decent but not maxed RC. Every point of Haste you don't have for BZ(Dusk+1, Speed Belt, etc.) will have a significant impact while it's actually quite easy(assuming you have Homam) to cap RC Haste.
