You'd also have to change the intro. There's the bit where Jack sends you to feed on the bum and/or the rats specifically to heal up from getting shot.
That's a good argument, so I'll keep it like it is! Bloodheal is a bit erratic anyway, as I had to simulate it by raising auto-healing-speed for a short while.
Another thing to note in regards to blood healing is that in PnP it's effectively instant, limited by turn and Generation.
And if you really went down the PnP with this matter, you'd also end up going with others, ie Potence and Fortitude would be permanently active for free, Obfuscate would be free, Presence would be free and permanent, Dominate would be free, depending on version of core book used Celerity may or may not drain blood point per level used, Protean would be basically unrecognizable (the heat vision is permanent and free until dismissed, claws would take 3 seconds to grow but last until dismissed, and the thing about the remaining ones is that three and four don't exist in PnP and the fifth is a *level seven* Protean ability), it's basically all like that.
Blood Buff would also be essentially permanent, since it too is a "scene" duration ability, scene being very movie-defined in PnP so it's a flexible amount of dramatic time impossible to define in a vidya solid value (examples in V20 for example define it ranging in time anywhere from "conversation at a park bench" to "storming a Tremere Chantry"), but of more important note would be that Blood Buff would not even be as Troika made it: It would allow you to just keep pumping those stats all the way until 6, three points of stat up and blood burned per 3 seconds. So it's better to stick to keeping them working within Bloodlines' own context than to make things like a PnP system that Bloodlines was not made to emulate.
Another example of this not related to Bloodheal and Disciplines would be that in PnP vampires CAN soak Lethal damage with Stamina, it's solely and only Aggravated that they can't, and guns wouldn't really do much good except specifically at the head like Jack says because all firearms only deal Bashing to vampires and vampires HALVE that damage rounded down after soak too (even a shotgun or assault rifle is downright puny compared to household sharp objects with equal skill used, especially after Potence and blood buff gets involved, and both are nothing compared to Protean Claw; Bite also deals aggravated damage but it needs wrassling to be used first so it's not that effective but Potence Bite is basically the rabbit from Holy Grail). Gist is that WoD PnP combat is very annoying swingy rocket tag where either no damage is dealt or either almost all or all the damage is dealt in one hit. The way Aggravated damage factors into this only breaks the PnP combat further, so it's actually Bite Tag or Claw Tag (albeit V5 has done a decent improvement by cutting down Protean's early access to Aggravated damage and capping Bite damage at two).
