Blood heal is too strong and prevents non lethal resolution to conflict

Mirrored from discord, spitballing ideas on how to fix BH:
I don't think it should be instant. It should have a wait time of a couple seconds at a minimum and be interruptable by movement, being attacked, etc.
It should be the type of thing you need to retreat to do. Part of the issue of near-indestructible gen 7's is they effectively have their health pool several times over because of free and immediate healing, and the blood economy is not restrictive enough to temper this.
Every combat has to be drastic and lethal because the moment you knock someone down or injure them to a point of logical surrender they will mash blood heal back to full and just keep fighting. The typical natural means of de-escalation are completely absent from vampire combat right now and it's severely lame.

Some other ideas:
Broken bones and other serious wounds take additional blood or longer times to fix, possibly need brief rest in a coffin
Each successive use of blood heal takes longer to use, possibly first couple uses are quick and then it becomes difficult to keep using.
Make blood heal cost more relative to max HP so that elders need to use more blood to heal.

Resting in the coffin as a compulsion as one thing, but I'd prefer to steer clear of having it be a typical coded requirement, solely in the interest of observing an immersive, gritty atmosphere of "our world, but darker"; the coffin thing is cheesy, but I'm fine with it remaining the realm of derangements or compulsions.

Regarding the meat of the post; yeah, bloodheal is a bit ridiculous. The instantaneous nature of it along with it getting strong for the first three generations you drop only makes the problem worse. We're intending a generation rework in the near future, but I'm willing to serve as a mentor to someone who wants to rebalance bloodheal since I have a few things higher on my priority list that I've made obligations to already.
