I think that is because Delirium has a way shorter animation lock than Blood Weapon or Inner Release. In 4.x Delirium just extended BW/BP duration, its animation barely noticeable. (tbh I wouldn't have known that DRK in the ShB job trailer used Delirium, it looks so "slightly")

Afaik if your GCD is not faster than 2.46s, you are not able to get 5 GCDs into a 10s buff window. Even 2.45s GCD is hella risky, as little lag spikes alone can rip away your chance of getting the 5th one in. 2.43s is more doable, but still requires good ping. 2.4s-2.37s is comfy.

Anyway, a 2.5s GCD build should not be able to get a 5th GCD into Delirium - unless the duration is longer than tooltip is telling us.
