What is the use of all talents?

Yesterday, I took my Tempest hound to adult with Power pip chance and Storm-proof. I am a little happy about it since it doesnt give bogus stats like helion over here. I found out that after epic, your pet will have 4 talents. So, what's the use of the other ones? It's a waste of Graphics, If you think about it. I say, after a level, our pets would have TWO talents learned aside from Derby talents. Right now, I have to train my tempest hound on Strength, Intelligence, and Agility since it boosts the power pip and storm proof up.
