[FIXED] [General] Castable while moving channeled spells vs knockback

[Pinocchio Evreiesc]

WoW Freakz spell link: All channeled spells that can be cast while moving by nature or via talents

Bug description: They get interrupted by knockbacks, it shouldnt happen. I can only speak for what i have been able to test, evocation and missiles get cancelled by knockbacks even with Slipstream

Proof: Ill upload a video from freakz soon, also a quote from a bnet forum discussion confirming that slipstream should allow those two channeled spells to not be interrupted by movement or knockbacks.

Quote:

For Arcane, it's likely going to compete with the new talent Slipstream, which allows movement while Arcane Missiles and Evocation are being channelled. The possibility of not having Evocation cancelled early by accidental movement or knockback effects is going to be very appealing to mages who constantly worry about that sort of thing.

Confirmed.

I love Slipstream. For instance, last night I was doing Darkheart Thicket and was fighting the boss that periodically blows everyone back into the eggs (downdraft).

It works ok vs those kind of pushes like dresaron's push or Elerethe's, where it stops working is on knockups / knockbacks that actually throw you in the air.

We already had a sort of implementation for this: if you are knockback, we don't cancel casts if you have an aura that allows walking while casting that specific spell.

Added 2 new rules: the same as seen above, only for "channeled" spells and added handling of auras that allow you walking while casting ANY spell (for example: Slipstream allows casting 2 specific spells while walking vs Surrender to Madness allows casting any spell while walking. these are two different types of auras).

It should work properly now
