I think you misunderstood the last changes to Invocation and this topic, after they added the missing notes.
Missed Patch Note(s)
- ‘Invocation of Death’
- Can now only trigger once per attack.
Dev Note: While class Abilities are really fun to use and a key part of a character build, they are also balanced around their cooldowns.
However, the Abilities cannot find a healthy balance when the cooldown can vary by large degrees due to Ability Cooldown Reduction effects.
We are therefore looking to rebalance the Ability Cooldown Reduction instances which result in extremely high uptimes of Abilities.
Invocation of Death, combined with the Zealot’s crit-focused kit, led to unhealthy situations when paired with huge cleaving strikes into multiple enemies; the new version will still be a really valuable pick in the talent tree, but not as overpowering as before by normalizing the amount of cooldown reduction awarded to players when fighting elites or hordes, with single target or cleave based weapons.
