From my perspective (played H1 since 5vs.5 and normally ranked top 5) the Problem with the never-to-be-seen Ultimate ist more a meta problem. The fights with HMF got quite fast. Before HMF dropped I did see the Ultimates more often. And actually it was a race against time, because the Executrix Ultimate (witch was the capitlal I fought 95% of the times) actually did end the match most of the time. So from the perspective of a former non meta player they are ultimate enough. But yes, i can imagine, that an Executrix player didn't see the ultimate quite often, since the inherent damage boost made fights quite fast and easy I guess.
