The fighters guild ultimate is only there for the 3% extra damage passive but you most likely want to use the charged atronach.

You can mix and match with light armor if you want (Light Slimecraw head for exemple) for more pen and crit chance

When you run solo, you can take Trap out for Carve. it's a good DoT that stacks 3 times anyway and minor force might not even be necessary in group so, it's up to you. It also gives a decent damage shield and could even replace your spammable if you'd like.

To optimise your rotation in group:
- Run daggers instead
- Run Weapon Power Pots instead of crit surge and camo hunter
- Run Clennfear instead of Camo Hunter (It's also a solid self heal so, def suggest running it)

To optimise your build for solo content:
- Do run crit surge for the heals
- Do run Carve or Brawler for the damage shield
- Again, Clennfear is a neat burst heal but you could run vigor on your backbar (The green morph) and keep camo hunter on your front bar to avoid having to bother with weapon power pots
- Use the ring of the Pale Order and put a piece of Kinras in place of the kilt to keep the full set

Alternate front-bar sets:
- Advancing Yokeda (Hel Ra Citadel)
- Briarheart (Overland: Wrothgar)
- Diamond's Victory (Crafter: Blackwood)

Alternate body sets:
- Vicious Ophidian (Hel Ra Citadel) - This is mainly for solo content. The sustain is nuts with this set on.
