Power Block has an internal cooldown that it shouldn't have

[Quadox.7834]

Power Block currently has an ICD on the weakness and damage (but not on the skill cooldown). This is unlike how it worked in the past and unlike how for example Pulmonary impact and Lightning rod works. It has been this way for a year or so, probably since interrupt traits were changed to work with defiance bars. I suspect the defiance interval was then wrongly applied as a general internal cooldown. This affects mesmer gameplay a lot.

Steps to reproduce:

1. Interrupt enemy, powerblock triggers.
2. Interrupt enemy again within 3 seconds, powerblock doesn't trigger.
