Heavy Barrage cannot be cancelled with parry.

[bog.witch]

Prior to the update, pressing the parry key while channeling Heavy Barrage cancelled the channel and instantly started the Parry.

After the update, you have to cancel Heavy Barrage before you are able to parry, otherwise you will get the "You are busy" prompt.

Unsure if this is intentional, but it feels clunkier to me now.
