So my friend, his guildmates, and I might head out on a Shadow Lair Snarbolax run in ten days. Seeing as I usually solo and build my loadouts around solo play, I want to see if I'm ready to play in a team.
Weapons (weapon alignment: swordsman)
Combuster (main dps weapon)
Final Flourish (for the wolvers and Snarbies)
Voltaic Tempest (limited crowd control capability, AOE damage effect, disables kats)
Polaris (turret suppression and knockback when I need it)
Alternatives
Shivermist Buster (more crowd control than Voltaic Tempest)
Argent Peacemaker (less team-annoying sidearm)
Divine Avenger (possible replacement for Combuster)
Armor: Skolver Cap, Vog Cub Coat [Skolver is fine, should I trade out the Vog Cub piece for something else?]
Shield: Barbarous Thorn Shield or Dread Skelly Shield [which one would be better overall?]
Trinkets: Elite Sword Focus Module, Elite Quick Strike Module
You're pretty set, although another piece of Skolver or some shadow armor would be better than the Vog coat. Shiver vs. Voltaic is personal preference. Dread Skelly's the safer choice over Barbarous Thorn Shield, but if you're comfortable fighting Kat swarms and Howlitzers with BTS then either works.
