So... that means that instead, they should allow the Circle to use blood magic because then the Harrowing would be unnecessary... since blood magic (supposedly) doesn't open the caster to the Fade in any way.... is that what you are suggesting?
I was debunking another poster's assertion that blood magic as a rule opens a mage to demonic possession when the school is embraced for the exact opposite reason. Blood magic is the safer route. I wasn't using it to debate circle politics - I was stating a fact.
But, yes, the circle should employ blood magic wherever possible in addition to standard spellcasting in a range of disciplines for its very useful practical applications. And, yes, rather than condemn a mage deemed too "weak" to resist demons to tranquility, I would endorse their learning blood powered magic as it carries no risk of possession.
Its too powerful a school to waste on fear. I wouldn't suggest using only blood as fuel, however. Its impractical and dangerous for all mages to use only blood as a power source. Too much blood in one area, and battles have the same effect, can rip the veil.
Too much magic in one location period, especially over long periods of time, thins and eventually rips the veil - that's why many circle like the white spire, for example, have thin veils - but as magic is too useful to eradicate, circle towers exist. The same consideration should be applied to blood magic.
