They currently suck and I don't know anyone who uses it. If i did, I would probably laugh at them asking them why they wasted skill points on them. Compared to just every other Epic Moment, it is garbage. It is not even as good as the tier 1 abilities for Shiradi Champion.
So, please consider making rain of arrows a cool down elimination for manyshot; with a 5 minute cooldown and a kill counter or skill counter like every other destiny has. You can have it a 10 rolls of a 20 like Unbridled Fury or whatever the case, but change it. The damage is putrid IF it hits and a certainly not worth of being called an epic moment.
Audience with the Queen is just plain bad. Bad idea and bad execution. Random effect of mediocre results that requires a high skill of something rangers typically don't build for = bad. I would change this around to be an effect, which you should be able to choose between when aquiring the skill, that enhances the two things this ED is based on... spell power or ranged attacks. AwtQ could grant a certain spell power increase for a duration or an attack and/or damage bonus for a duration. Again, tie it to a cooldown and/or completing a certain amount of attacks or spell casting etc like all the other good epic moments.
The way it is set up now, it is a total and complete waste and a joke why it even went into the live game considering all the negative feedback it got during beta.
It is time to do the right thing. Maybe less development cycles on creature companions and make some real fixes to the game such as this and others in the ED system that you charged a pretty penny for.
