@Medhia_Nox: Your missing the point. The skill its self is fine, no one (well not in here, anyway) is looking at the skill and scoffing at its impossibility with in a world of fireballs and warriors making fissures (least game mechanic wise, they're split after all, well to some extent). It's that they have said all specialization skills aren't dependent on a specific weapon type. If you look at all the artificer skills, this is true except Hail of Arrows on Varric (which is in the Artificer tree).
So the question holds, is that 'just' for Varric as hes, story wise, meant to be an archer? Or do all Artificers (aka, the Inquisitor) also get this extremely bow focused skill when all the others work with or with out a bow (or daggers for that matter). All I'm curious about, really, and if it's just for Varric, does it mean all companion focus skill is unique to them while the other specialization skills aren't? Just has me curious is all.
-edit-
I should also point out the Hail of Arrows is a focus skill, not a normal skill. So it could very well be different for the Inquisitor, hence the question at had.
