General

@jenno: IIRC The rapid fire argument is it's both constant damage and you can move during it. Gives some advantages over a skill that you use repeatedly (ADDs absorbing hits is one). Hurricane and RF are equal but RF let's you move at 120% vs hurricane's 100%. When the update from kms that boosts phantoms comes this topic will be pointless though.

@catthewhale hope it helped c:
hmm with 65% crit rapidfire would be at 13.75 hits/sec and blast would be around 12 hits/sec.
at that point (assuming you don't cap) it would depend on the %dmg per line of each skill.

I'm not a phantom but every phantom friend I know uses rapidfire.

@jenno: thanks man EXACTLY what i was looking for.
With cards into account, rapid fire/blast r quite close. I guess i'm gonna use blast since i only have 65% crit to prot cards.
Would u agree with me?

seems like blast and dark impale attack about the same speed @ normal (6) 840 ms
+/- 60ms for increase/decrease in wpn speed

EDIT:
I'm assuming you're a phantom wondering which skill to steal, so no hypers will be included in these:

hurricane/rapid fire is 8.33 hits per sec
mille aiguilles is 11.11 hits per sec (after next balance, 15.38)
blast is 11.11 hits per sec assuming faster (2)
dark impale is 9.52 hits per sec assuming faster (2)
angel ray is 6.50 hits per sec assuming faster (2) (not so sure about this one)

these numbers are without final attack/flying cards, so if you take those into account I think these numbers would help more:

hurricane/rapid fire is 8.33 seperate attack animations per sec
mille aiguilles is 5.56 seperate attack animations per sec (2 lines per attack)
blast is 1.59 seperate attack animations per sec (7 lines per attack)
dark impale is 1.59 seperate attack animations per sec (6 lines per attack)
angel ray is 1.59 seperate attack animations per sec (4 lines per attack)

(someone can correct me if I'm wrong)
