General Windarcher

Inner Ability So earlier today, I was rolling my ability and happened to get [url=http://prntscr.com/85v0mk]this[/url] I was wondering if %boss or %buff duration would be more beneficial Note: I do not have (2) 25% boss nebs which I am trying to get. Also, for the recent class changes wind archers will soon get an extra 40% boss I felt that since by boss damage will be close to 300 after those changes, the buff duration would be more beneficial, but I dunno What do my fellow wind archers think? c:
