I on the other side want him gone. I don't need a sex pest in my camp. He literally has nothing going on in act 3 at all and act 2, he feels sidelined too. He can cure the Shadowcurse, yes, but overall, Jaheira feels, like she is truly the one, knowing her way around despite Halsin, according to his own words, have been there at the first attack at Moonrise.
And you can't refuse him. You can refuse every other companion but not him. It is frustrating.
I do agree that being forced to have a sex pest in the camp is a bit of a problem, and I truly hope they will fix him one day so that he'll actually become the mature and wise man that we were basically promised in EA (and kind of in ACT 1 and 2). I also agree that he should not be forced upon the player. Let people who want nothing to do with him reject him without actually having to kill him. He could head to Last Light Inn on his own if player doesn't want him in the camp and meet them there to help with the Shadowcurse if need be.
But I also do think that he should be recruitable after the party in ACT 1. There's really no point in having him stand around in camp all this time doing just about nothing.
