WILLPOWER PRIORITY
Bombardment > Burst Fire > Balder's Vengance

Bombardment and Burst Fire have around the same priority, however Burst Fire is easier to use so slightly higher utility depending on situation. However Bombardment THEN Burst Fire is always higher DPS assuming optimal conditions. Use Balder's Vengance smartly. Save it for dungeon mechanics, or a finisher. There are obviously exceptions to that, but that's up to the player. Just play smart.

Guaranteed Willpower
Arcane Barrage > Scattershot > Replenishment
400 Willpower

Basic
Mana Missiles > Arcane Barrage > Scattershot > Replenishment

- Use Sentry Turret as engage, Burst Fire is your filler when other Willpower or Willpower building skills are down.
- Excluding the Willpower building, and Willpower skills themselves, doing "ANY" other "DPS" move is a dps loss.
- Use Rapid Fire if Mana Missiles, Time Bomb, and Arcane Barrage are down IF you have 14 shots or above. (980/840 Willpower) Otherwise Scattershot does more.
   - Cancel Rapid Fire immediately if Mana Missiles or Arcane Barrage are up.

Damage example of why CDR is good
10 sec skill
 - 100 damage

CDR - 8 sec skill (20% CDR) [obviously would be 22.2% w/ nostrum and one roll but just making numbers even.]
 - 90 damage (10%) loss (lost enraged damage, it's less than 10% lost due to attack modifier difference but again, I'm just making it simple.)

- 1 minute fight

w/o CDR - 600 damage

w/ CDR - 630 damage

-2 minute fight

w/o CDR - 1200 damage

w/ CDR - 1350


EX #2 More realistic for what I'm describing. VM5 Example CDR x2 vs Enraged + CDR
Base Damage: 100 (before enchantments
10 seconds

Enrage + CDR: 109.3 22.2% Speed (7.78 seconds)
CDR x2: 100 29.4% Speed (7.06 seconds)

1 Minute - CDR WIN
ECDR - 7 attack rounds: 765.1
CDR - 8 attack rounds: 800

2 Minutes - CDR WIN
ECDR - 15 Attack rounds: 1639.5
CDR - 17 Attack rounds: 1700

3 Minutes - ECDR WIN
ECDR - 23 Attack rounds: 2513.9
CDR - 25 attack rounds: 2500

4 Minutes - CDR WIN
ECDR - 30 Attack Rounds: 3279
CDR - 34 Attack Rounds: 3400

5 Minutes - CDR WIN
ECDR - 38 Attack Rounds: 4153.4
CDR - 42 Attack Rounds: 4200

6 Minutes - CDR WIN
ECDR - 46 Attack Rounds - 5027.8
CDR - 51 Attack Rounds - 5100

tl;dr, the longer the fight and the longer the cooldown, the more CDR pulls ahead due to gaining extra attack rounds. And every fight that's relevant is longer than one minute. MP is a non-factor due to Dyads, and MP being on the weapon itself (VM5). CDR on weapon also affects ALL skills, even ones nostrums do not affect. It does NOT affect Brooch cooldown. That is an item.
