Companions are a core component of all of the primalist masteries and are prevalent throughout them. One of the primary functions of a companion is their unique ability you can activate.
I think the transformations of the druid need better ways if using those abilities. I understand the devs not wanting people to stay permanently transformed and encourage switching back and forth, but for those who want to stay transformed, there is a limited number of ways to activate companion abilities.
Maybe allow the player to replace a transformation ability with the companion abilities, allowing players who dont want to switch back to human form a way of easily activating their companion abilities, this could also make it easier to resummon a companion should they die and you cant revive them without the need to detransform, resummon, and transform again.
