Can't comment on romance stuff or his questline, as I completely ignore Halsin because I find his whole behaviour unbearable and disgusting. Bear sex, really? But that is not the point I want to make. I find Halsin genuinely useless. By the time he is actually available as a companion, you already have a druid available, and Jaheira is way more interesting to me. And you definitely want to have Jaheira around for parts of act 3, so I'm not going to have a 2nd druid in my party. Apart from that, druids aren't the most useful class, by the time Halsin can do anything for me, I have way better frontline fighters, way better healers and supporters and way better casters. So either bear dude needs a major overhaul, or he should be reduced to a quest giver. And maybe remove the bear thing?
