On paper this spec is awesome. In practice it's pretty rubbish. With a few small tweaks it could really shine though.
Dodge
I understand the thought process behind this (~0.75 second per 50 endurance), but in practice it feels very, very bad. Instead, just make them all 0.75 second and 50 endurance like Thief, but give us only 1 like Mirage. Adjust numbers slightly, as they are already pretty underpowered.
F2
This feels like a nothing trait. I'd rather have the core trait for free energy to be honest. The dodges are not high-value enough that I am desperate to fire them off constantly, and switching every Alliance skill to it's exact opposite is not what I want. I want to be in Kurzick OR Luxon most of the time, not both. This should really be split out or totally reworked as others have suggested. Also the energy cost is very high. 50% of your starting energy is a big ask. It also doesn't feel great on other legends.
Traits
These are the least impactful traits I have seen and that is saying something. Add more damage modifiers and interesting traits.
Adept
Zzzz. These are very underpowered. Amnest is the wrong way around and should offer much more might (2 - 3 stacks) and kurzick should remove a condition or something better than a few seconds of regen.
Master
The master line really all does the same thing in one way or another and this doesn't really create fun options. Song of Arboreum looks to be mathematically the best anyway. Add a big damage modifier and something to power up Greatsword.
Grand Master
As mentioned in the doge section, these are okay but the dodge time is too long. They need some tuning and all to be on 1 0.75s dodge at 50 energy. Reduce uptime to match.
Balance in Discord
This is also a nothing trait. 1.1k health and some regen every time I swap. Okay that's kind of nice but throw in some might or something interesting and we're talking. Alternatively scrap it entirely and move one of the Master minor traits to this slot and rebuild the whole Master set.
Empire Divided
This isn't too bad. They probably need a bit of a tweak but it feels a lot more like an Adept or Master tier minor than Grandmaster.
Skills
These all feel quite clunky and slow. I don't like the CD on swap. The skill that should go on cooldown should be the one you just used, not the one you are about to use. This will reduce a lot of the clunkiness.
Heals
They're fine but that's about it. They need a base heal though.
Battle Dance/Nomad's Advance
Battle Dance should ditch the wind-up. Nomad's needs a more might on cast, or could gain similar functionality to Facet of Strength where it gives you a buff on use. Really it's just very underpowered.
Scavenger Burst/Tree Song
These are pretty solid but could use a bit of a tune up. They feel underpowered. 5 seconds feels more reasonable for quickness and the cast time is a bit slow. Tree Song could use Swiftness of like 8s.
Awakening/Reaver's Rage
Boon durations are just way too short. They need a big buff. Also cast time should be removed. Why is a stunbreak on a cast time? Blergh.
Spear/Urn
Spear needs to hit way harder. Twice the damage. Urn needs the ability to double tap and the constant damage needs to be reduced by 50%
Greatsword
Underpowered and slow. It's like reaper GS but worse. Mist Unleashed should hit significantly harder, as should Phantom's Onslaught. Eternity's Requiem should offer yourself Might or Fury or something.
Summary
The spec mainly just feels slow, clunky and underbaked. It's hard to get at the abilities I want and when I can get them, they don't even feel that good to use.
