Pallagina in Paladin/Chanter mode. Her buffs will be most beneficial for you character, and might as well help Eder.
Maia Rogue/Ranger is fair deal. Just Herald will bring more for you.
would it be too crowd on the front line?
Currently my party has Eder, Aloth, Xoti, I am a shifter barbarian, for the last slot in my party, which companion you guys think would be better to my party, Pallegina,Maia or Serefan?
Just wanna start my first run through. Which class do you think would have more fun, soulblade/ barbarian or shifter druid/ barbarian? or is there any other suggestion.
