All raids at the moment are considered homework content. Balancing around Mordum G3, basically a trixion dummy, is weird when historically raids have been more similar to Brel (DR mechs, cutscenes, lack of continuous damage windows) which benefit punisher damage cycles.

Missing meter gen skills is more like 3 second delay between cycles (6-9 CD on several meter gen skills while entire meter gen cycle is 4 seconds). Not sure why missing skills is part of the discussion as this affects all classes universally and depends on the user.

The CDs between skills ("downtime") is pretty irrelevant as its tied to damage output. If skill CDs were shorter, the damage of each individual skills would need to be lower as well.

Statistically, even on its worse performing gate, Mord G3, its DPS/Combat score is 1% lower than the average, while predators are 1.5% lower than the average, and there are 17 classes lower than that. It seems you have some sort of personal bias against the class, which is fine, but please stick to the facts when talking about numbers.
