1) She is not weak, nor incompetent, she is capable and useful as is.
Useful puppet, I see. What will we do when it will become obvious that we don't convert her not because we have no suitable gifts but because we don't want to?
2) While i think that we should keep him as an ally, i do not believe that we should do things just because he wants us to.
OK, let's not do it, we will just anger him, he'll take his daughter away and use her in other useful way.
3) She's not the only potential ally out there.
Key word is trust. We may find someone later or we may not
1) Those skills can just as easily be turned to help us get other mates, and would not improve through turning.
I don't think so . Reread the description of the gift. Night troll will get some trait
s based on female converted. I think traits would be based on skills, genetics and character
2) Her family has disowned her, and i think that if we make the gesture of allowing her to maintain her humanity, we will have earned her undying loyalty, and perhaps the loyalty of the tigerwoman. On the other hand, if we turn her, the tigerwoman may come to hate us.
We'll either have to fight with her angry father or convert her sooner or later. Don't you see that? And mortal inside a big family of night trolls... is a bad idea. If not we, one of our sons will convert her or one of our consorts will kill her. We may let her run away of cause, but that equals to losing an ally, too
3) she can do this as a human
She can do that better as a night troll
5) We've gone through the game well enough without this, and even before we had our consort Weirdsound assured us he had a method of continuing the game.
Surely he does. But let's think about better restarting conditions
Edit:
Also, who knows maybe Alice will get a trait that will make her able to mate\convert with both genders? Or only female ones. It's suitable for her background... Then we may share our consorts
