This spec feels like it's doing too much, almost like what Firebrand has turned into. It's got ranged DPS, melee DPS, boons for you, boons for your friends, mobility. Shroud refills super quick so you can spam it continually. Most of the skills had quick cooldowns in an organized comp. Very much a jack of all trades, master of nothing feel for PvE. Having a healer in the comp completely removes the challenge of trading health for damage. It was fun to play but also unsatisfying.
And a very personal comment that I think only I care about - the icons for the Harbinger utility/healing/elite skills are disappointing. Engineer elixirs all have their own unique icons, but Harbinger's are the same shape just copy/pasted with different colors.
