Want some good insight? First off I know it’s any one’s choice but the thing is , if you choose Ashley in ME 1 and unless you don’t romance her…..in ME 3; she doesn’t have a lot of dialogue like Kaiden did. I have tried it both ways when I played and still playing LE and back when the original trilogy was out. If you don’t romance Ashley then expect to not get a lot out of her. Not just that but also Kaiden is versatile on the battle field with him being a sentinel. He has better abilities in ME 3 than Ashley does.
