I have read and even partcipated in many of the various vampire threads.
I understand people on both sides of the fence very much want control over how their character looks.
My thought for a middle of the road, works with the Justice System, idea would be to add another skill to the vampire line.
Blood Thrall with 3 buyable ranks.
This skill reducese the aparent stage of vampirism while in town. Visable stage is reduced by 1-3 levels.
Being at stage zero would be the normal character look.
It would be assumed that though that evil blood sucker that you are, someone somewhere is enslaved to your will to slake your thirst in town.
One rank would be enough - I hope - to keep city guards from killing stage 4, but otherwise law abiding undead from being killed on sight.
The grat thing is that it would be entirely optional - have a cost, thus making it fair, the cost would, in the sceme of things be pretty minor.
