Werewolves are dependent on the moon for their transformation as we saw in Season 3 when Boyd and Cora were trapped inside the Hecatolite vault.

Deprived of the moon's cycle for so long made them more animal like.

The smooth monthly rhythm evens out their transformation and gives them more control when the moon is waning or waxing, less control when it is full.

Without the moon to temper them, give them more control, the berserkers are all crazy animal all the time.
