Soren was always a liability in my playthroughs, but the magic is just so much fun. I never use more than one mage.
I forgot to add Kieran, he's powerfull as well.
I see I'm the only one that likes the Laguz. Their leveling is bad, but I love their power.
Volke has by far most avoid, and always gets to double attack, so despite low stats you don't really have to protect him.
Can't wait til Radiant Dawn FINALLY releases in Europe.
