I found myself sticking to Shulk, Reyn, and Sharla. I feel like i should switch out some people and try others. I did with Melia and shes alright, and i really dont want another swordsman out there.
suggestions?
Melia is great as a player controlled character and a very poor CPU.
Riki is great in both rolls. As a player controlled character, he can really control the battle. He has massive HP, can do a lot of damage, can inflict status, steal items, drop all aggro at once, heal your entire party.. a very versatile character.
Shulk and Riki were my two main characters my first play through. I'm using Melia on 3D now as I understand her character a lot more, but I do switch off to Riki from time to time as I enjoy the change in battle activity.
