Nerfalems, recently found these:

How to roll? avg dmg or 10%

There are some "experiment" done by those China player stated 46% of CDR is the best, but actually I not so sure how best it is, so just make as much as you can, Glove - 8%, shoulder - 8%, helmert - 12.5%, both weapon - 20%, Paragon - 10%

You can look on those people on the high Great rift top rank, mostly have CDR on both weapon (I didn't check top rank player for 2 weeks, but the equipment attribute should be the same)

PS: Oh ya, if put on Gogok of Swiftness gems (level 25), u will get another 15% CDR

Usually is Calamity or the Fire crossbow, see which 1 you have it. Please note that the damage of the RoV will only depends on your damage of main weapon. means if you have high dmg calamity, please put as main weapon, then put the Nat Slayer as assist weapon.

Rune of VoR normally is Stampede for solo, and Anathema for group, never use Stampede in group, you might get kick by your team member, unless the other members are all DH, then it might be some exception....

The crashing belt is important, need to get as near 4000% as possible, even though the other attribute of the belt you get are sucks.

You can just refer to those top rank player.

Yes with - F+R, wolf and BBV.
