Personally, I understand the salt. Melee Scouting DPS or Healer would have made way more sense to me.
The fact SE went with Ranged DPS makes sense if they plan to go hard on the support aspects to match Bard. However, that also worries me because of the same things that make Bard broken at the moment. Hopefully they don't do something like Crit-scaling procs again.
My primary concerns are seeing how they manage to make it unique and the usual balance concerns. As long as they don't make it as busted or broken as the other two Ranged DPS we should be okay.
That said, I'm happy they're being added. They look like they're going to be throwing weapon based too. Chakram was spot on, so good to whoever predicted that.
