I'd say that this goes for pretty much all the minor Asgardian characters. They don't necessarily get more screen time but they shine more with what they have.
See I find this topic interesting. If you involve the Warriors Three more, then you're getting into the "quest" style movie like LOTR. That is not what they're going for here.
Wanting more from fun characters isn't necessarily a negative.
