Question about the Gorax

[Bloodwind]

The animus Primal on the Gorax states that the affected beast frenzies during your next turn. It no longer specifies that it happens regardless of what has happened since the animus was cast.

Target friendly living warbeast gains +2 STR and MAT for one round and automatically frenzies during your next Control Phase

If Primal is dispelled or replaced does the beast still frenzy?

[Bloodwind]

oh, and this has been debated in here and everyone agreed that it had to go to an infernal ruling, that is what I'd like.

[blue loki]

It must still Frenzy when dispelled as otherwise Primal would never cause you to Frenzy, ever.
Primal is always removed from the Warbeast (step 2) before it Frenzies during your control phase (step 3/4), even if it is not dispelled by some other means.

[Macallan]

Tactical Tip that you will see in the book:
Primal — The warbeast frenzies even if Primal was removed via a spell, ability, or casting of new animus on the same model prior to the Control Phase.

Or something close.
