That is a good point, about the supernatural abilities! Didn't think of that.
Apologies for resurrecting this discussion several years later - but just to note that we took this feedback on board after further playtesting and have updated the rules. Vampires now start with 1d4+2 composure instead of 1d6. It's only a minor change, but means that vampires can now typically expect to take one "hit" before losing their composure - which encourages a bit more experimentation. Thank you again for your review and feedback!
