Having it as option would be great, but I feel as if this will be a plot point, (the' need to be cured' comment I saw you make on an old thread long ago for the mc) Forcing it makes me not keen as it would mean whoever you hitch your wagon to will pass away and you will still be your same dreamy self moping around the place.
I could see it being a factor in Loren 2 due to Samaras, but then in Cursed Lands it would depend on how the storyline plays it out. Do I get to kick my sires teeth in for having turned the mc? Because that would be pretty damn cool and fun.
