AW spells (Chain Lightning, Stonefist) deal good damage.
Compared to what? Really.
Simply saying it doesn't make it true; Put it in context against other skills that can be used at least as often, or more often, from well geared characters.
Try comparing against Payback from a Legionnaire with Caliban and a Dwarven Proving shield, Flow of Battle and Walking Fortress for cooldown reduction. Don't forget about Blood Frenzy and Cutting Words.
Payback from a Templar with the same gear, Horn of Valor, Blessed blades with Lights in the Shadow, and Flow of Battle. For giggles, since you've got two powers, give the Templar a Dwarven Crusher and hit Spell Purge after Payback Strike.
At risk of sounding ridiculous to you, compare against a Reaver with Sulevin Blade, Rampage and Dragon Rage, with Scenting Blood + Coup de Gras opening with Mighty Blow then unloading.
An Archer, just being an Archer.
An Elementalist milking Flashpoint, Energy Barrage and Meteor (zero downtime).
A Keeper with Chain lightning and Fade Cloak (who can also have Twisted Veil, Static Charge, Conductive Current AND Clean Burn).
Most of those characters are also doing way more damage with auto-attacks between skills too, do I really have to make a full list, or are you still 100% convinced AW is somewhere near the top for damage?
Oh I forget, when AWs deal damage, they are non-stop spamming their abilities and hitting the maximum number of targets in neat little 5-man groups and nobody else ever gets to attack (they are.. running?) so their DPS is zero.
AWs never have a split pull with two mobs, then three more than run in one at a time - that's a problem that other classes have to deal with.
They never have a waves of mobs coming in 1-2 at a time at three different targets in 5/5, that's also a problem that only other classes have to deal with.
When AWs corner-pull, they can wait at the corner, other classes have to prepare themselves for a 10 second run-up.
When AWs break line of sight, they maintain line of sight for their own attacks.
I'm obviously being facetious here, but my point is you keep counter-arguing the damage output of other classes by saying they don't always get ideal conditions, or even that they are nearly always faced by conditions where they can't do damage at all, completely overlooking the fact that AWs also don't always get ideal conditions. Unless I'm playing with a couple of Beast Archers that I sometimes get the pleasure of following around or I'm way under-levelled, I don't ever find myself spending most of every fight doing zero damage regardless of my class - and certainly never because an AW is in the group.
Initially there were angry demands I demonstrate my claim of 3x fade cloaks in 12 seconds. I later showed video, and there's only jealous snarky remarks afterward accepting proof it was done. You'll get about 4-5 SB swings in that time, or roughly 20x weapon damage. 3x fade cloaks is 30x alone, plus two-three spellcasts, and detonation damage, and all bypassing being blocked. SF actually does more damage than SB (5x + weaken vs 4x) -- both animations taking roughly equal time-- plus paralyze --> detonate from static charge.
I have not seen the video, but the build seems fun.
Is that 12 seconds counting from the when you come out of the first Fadecloak? Because if not, I'm amazed you find the space for so much cooldown reduction while also slotting Stonefist + CL into the rotation. OR is it that Fadecloak can be cancelled before the 3 second mark, in which case you for real taught me something and blew my mind.
The 500% Spirit Blade was my legit mistake, it's 20% worse than I thought.... 
Very few enemies cannot be paralyzed. Let that be known to all
Or put to sleep
