Skill Explanation:
Bar 1 - Sword and Board: You ideally want to use this to apply pressure while staying tanky-ish
Toppling Charge: Gap Closer and Stun, usually will use this as an opener
Blazing Shield: Use this once you're in close, ideally against a group of enemies, to be tanky and set up some burst
Total Dark/Blazing Spear: If you're running with some Stamina hungry people, blazing spear is probably best. against sorcs or other projectile users, Total Dark will be best.
Elemental Weapon: you'll basically spam this skill for your main pressure application. Use the skill, Light attack, rinse repeat as much as you can
Radiant Oppression: Execute ability. 'Nuff said.
Ultimate - Shooting Star: Strong burst with a ground AoE afterwards.

Bar 2 - Resto Staff: This is for healing as well as Magicka Sustain when needed.
Rapid Regeneration: Heal you probably want to keep up as much as possible, solid numbers and fast ticks on the HoT
Purifying Light: Can set up some MAJOR burst in a small group if you focus the right target, with the added bonus of some leftover heals.
Siphon spirit: Apply this to the main target to give Health and Magicka sustain to everyone who attacks them.
Extended Ritual: A nice heal but more importantly it cleanses harmful effects. Use when we are hit with DOTs and debuffs, allies can use a synergy and you automatically cleanse 5 negative effects.
Total Dark or Dark Flare: I prefer Total Dark for Added sustain and to try to get them to be less aggressive, but Dark Flare is a bit of Ranged damage, along with Major Defile (Reduces the healing they take) AND empower. Ideally use this before swapping to your execute on your first bar.
Ultimate - Life Giver: A big heal along with a buff. Could also use the Restoring Light Ultimate if you prefer.
