tl;dr

Changes I would implement
  • Remove cost of stance swapping
  • Storms Eye now generates 20 Gauge
  • Storms Path now generates 10 Gauge
  • Storms Path now reduces target damage dealt by 5% for 10s
  • Infuriate is now usable out of combat
  • Beast Gauge depletes by 5 every 5 seconds when out of combat
  • Onslaught Aggro Modifier halved
  • Onslaught CD increased to 30s
  • Onslaught now generates 10 Beast Gauge, using it does not cost Beast Gauge.

WAR is missing out on a lot of utility. Returning a weaker Storms Path to the kit would make the class more viable in 8 man content.

To ensure that Path is not being overused, the extra Gauge generation should be given to Eye.

Generating stacks between pulls is not a bad thing. However, to make sure WARs dont keep the group waiting for a minute to generate 100 Gauge, it should fall off before Infuriate is back up again.

Onslaught needs to be improved imho, its lackluster compared to Plunge. I consider those changes good enough as a combat initiator and extra Gauge generator.
