So long as it can make up for the HP spent, that'd actually do fine. It'd be another thing that could go wrong (like mistiming CDs), but equally another thing that could go right (additional burst damage before damage lulls or ways to improve healing-received efficiency during damage lulls, and/or a way to more granularly prepare for damage spikes -- essentially banking HP during lulls for later burst damage taken).

though this is probably as an artifact of once having an MP-consuming Drain spell.
I have to agree. Such made BW far less susceptible to drift, as you could build resource at almost any time and every form of potency afforded by MP at least had some sustain value attached. Back then, it was a smart choice. It just stands out now that we can't spend MP on Sustain... which, honestly, your AD/Bloodspiller would rectify, if not for the slight damage loss of using them when you need healing rather than solely during raid buffs (which brings us right back to the old HW DA issue of maximizing direct potency over rDPS-when-accounting-for-healer-GCDs-saved... though that also comes down to healers having been largely changed since then to have very little GCD healing).
