BRD: Is THM sub useful?

[Arcell]

I'm not talking about CNJ. I was referring to THM in my OP.

So we are left with Resonance and Necrogenenis.

Will BRD really be nuking with THM spell for HP back? It's equivalent to using Second Wind, so I could see it as useful as an emergency heal.

And Sanguine Rite, arguably the most useful of the Thaum cross-class spells.
