That... just seems plain weird. Sanguine is working very well currently in its capacity as a boon for Dracul, and I'd be against folding it into the BLUDTUPOWA glyph's effect and then changing it to do something completely bizarre.
I like the current B2P glyph, the problem is that it synergizes too well with BURNDAYRAZ specialists and with Binlor and Mystera piety farming. Ideally I'd like to see B2P changed in a way that is less substantial than its recent nerf, though I'm afraid that might not be feasible by the nature of B2P.
