Well the only thing I can think of then would be to do a keyStatus “bleed” and have debuff for triggering a bleed based on an already bleeding target to allow a “stacking” of bleed on a bleeding target for an ability that normally doesn’t have a bleed otherwise. This allows for stacking of bleeds by abilities that normally don’t cause bleeds and not really affect other bleed abilities too much. Have to think about this a bit more.
Side note, using some of your classes too after I modified them. Basically The surgeon I changed around a bit some to be a bit more usable and balanced, and the Vamp I changed out an ability to include a debuff ability called Haunting Guise as a debuff/fear like ability instead.
