IMHO, I have played Lini and my brother Valeros.
We are currently on Adventure Path 6 scenario 1
(we play on Skype) I set up the game and he pulls cards as I turn them over so that we can play together.
So he covers the top part of the character the Melee stuff and I cover the magic stuff. we pretty much get through it with very few issues but well balanced.
Lini goes with 4 heals and 2 melee spells
Valeros goes with weapons and armor
