I don't think the issue here is whether or not it'd be viable DPS wise. If you check the Sims, barrage and MoC are very close single target DPS. The issue is multi-target as there are tons of mobs being grouped in the new dungeons. I agree that with Barrage and even Sidewinders it can be difficult not pulling additional aggro, but if you're going to be using PS you need to worry about placement. Maximizing DPS via PS would be difficult if mobs were spread and the movement required (sure you could disengage into position if you're good at it) would further drop your DPS . Barrage is similar in
