Making him a proper companion in Act 1 would be unfair to Minthara.
If recruiting Halsin is unfair to Minthara, it's already sort of unfair as is now since Halsin is with the player from the party in ACT 1 anyway. He's there with us no matter what we do and we have access to him as oppose to Minthara who we just have shorter meetings with until later on. It really makes no sense having someone in the camp that we can't utilize.
And to fair, being able to recruiting Minthara in ACT 1 on evil run wouldn't be such a bad idea either.
