Isblocking Condition does not function (crucible)

Summary

The isblocking condition will always trigger as false, no matter if your blocking with a shield or not.

Steps to reproduce

Create a skill that requires you to block with a mythicmobs shield, and attempt to block, it will not trigger.

Current behavior

The skill will not fire, debug will show that the condition was not met even if your blocking.

Intended correct behavior

When blocking, the skill should fire.

Proposed fixes

Correct the blocking condition to trigger properly when blocking.
