Gulk does not proc Regen from his sig ability in AQ

Of the hundreds of fights using Gulk in Map 6 AQ I can only remember once, maybe twice, where he proc Regen instead of Attack boost from his sig ability. However, in Event and Story quest its roughly 50/50 as the sig ability advertises. My play style does not differ in any way that could account for the discrepancy.
