Then you don't really understand how 4e powers work.And Hurricane of Blades is NOT broken either. Sure, you get up to six attacks with it, but you are only doing a single [W] worth of damage. Its a minion killer, but not very useful against the bucket of hitpoints that a 27th level non-minion monster is going to have. I'd much rather have Blood Frenzy and be able to dish out 5[W] worth of damage as my 27th level encounter power.

At 27th level your bonus to damage is likely to be much higher than your [W].
Even assuming only half your 6 attacks hit, with a 2d6 weapon (the best case for a higher [W] power), this equates to 6d6 + 6X vs 10d6 + X.
By 27th level, a character should have a primary ability of at least 21 - assuming a 14 at 1st level (most character will have at least 2-4 points more) - which equates to +5. Add the assumed +4-5 from your weapon, and X is looking to be at least 9. Average on 2d6 [W] is 7.
So we have (assuming only half your attacks hit) 48 points of damage for the 6[W] + 6X power, vs 44 for the 5[W] power...
If (the more likely scenario - normally PCs in 4e have a slightly better than 50% change of hitting) 4 of your attacks hit that becomes 64 points of damage vs 44...
If all 6 hit, it becomes 96 points of damage.
And that is in the best possible scenario for the 5[W] attack. Likely X will be much higher for any 27th level character, and it's also probable the weapon won't be a 2d6 weapon. It's also desregarding criticals - I don't think I have to prove that 6 attacks are more likely to score at least one critical than 1.

So not only is it the more flexible power (equally effective against a swarm of minions or a solo), it also has the higher average, expected and maximum damage.
How is that not broken?
