I was just watching the Fatboss video on Helya in Trial of Valor during the PTR, and saw a Marksman hunter PoV, and in his clip he successfully barraged a pack of mobs that was halfway down a staircase in Helya's large boss area. With the way they reduced barrage's z-axis range both up and down, I bet we're going to hear a fair more complaints about it soon with the release of ToV. Anyone have an estimate on how quickly they will modify Barrage again?
