Is the pets first skill going to be the strongest skill when it's fully evolved? or do they all scale to a max level?

My Main character is a Knight.
What do you think would be the most ideal 3 skills for the pet to have?
I'm leaning towards heal first

The first skill maxes the fastest, but the other skills eventually catch up.
I'd say heal or mp heal first. Mp heal starts at a lower regen rate than heal, so depending on how much fame you have/pet feed items you have, you may want to go with mp heal as your first.
For your 3rd I'd say electric or an attack. I would go with electric honestly, if you don't give a fuck about paralyzing the bosses in tombs (although the new animation is kind of annoying...).
I am not too sure how the new abilities are, but to me they seem pretty bad.

Agreed these were my same thoughts exactly

Ok perfect.

Now to find an egg with Heal first then Magic heal - electric in that order.

HP/MP heal, and whatever third skill appeals to you, if i could have it my way i would have rolled a HP/MP heal and Decoy.
