Generally I always create the animation in the Blender file and import the model with the animation into Unity.
Does anyone have any opinion on generating the animation inside of Unity instead of creating the animation in Blender? The model is already rigged.
Thanks.
@DavidGeoffroy has an opinion 
If you are looking to change your pipeline because you are having workflow conflicts with blender, you might want to check out akeytsu for animation purposes. afaik there free trial is open ended and has no limitations.
It sounds like even Unity strongly encourages to not use Unity to create the human animations at the moment.
I’ll stick with Blender I guess. I just wondered if I was missing out on something Unity had to offer WRT the animation creator.
