Curious, but is it possible to make a viable build by focusing more on the deepwood archer aspect of ranger? It seems to have nice stats, and correct me if im wrong, with enough ranged sneak attack and maybe some extra sneak dice from other trees couldn't you dramatically increase the power of multi shot by sneak multi shotting? Since your basically dishing out two sneak attacks per shot if you multi shot, thus its basically double shotting during multi shot...or does sneak attack not proc on a multi?
If that works it sounds like if you don't have monk deepwood would be amazing dps wise during multi. OF course this all comes crashing down if multishot dosent proc sneak.
