The power of depends on how often you can actually hit the enemies. I mean, you can easily match the damage of at level 18 with only, but that's only if you can proc  on the enemy consistently for 15 seconds--which is not easy.

Realistically you will be attacking the enemy 1/3 of the time that you are around an enemy if you are agressive. Since 1/3 of 15 seconds is 5 seconds then you would have a 7 + ratio at your disposal--since AOE drags for 2 seconds.

That said, since has a  ratio already, it would need to be subtracted from the  ratio to see how much damage you would need. That said, (180-7)/ is required to match the damage of  reliably at level 18. Which is pretty reasonable since a recommended build on gives.

So basically is perfectly reasonable to get. Just make sure you are pretty aggressive with abilities to get the most use out of.
