Hey Therefir. So you asked for some more concrete reasons for why CSRC should be recalced as melting, and I've responded here. The reasoning is pretty extensive so I'd rather not waste your time writing it twice. But TLDR, CSRC is described in the guidebook variously as a 'scorching' attack that 'shaves the crust' and Boros is always shown to melt things. So if CSRC is going to scorch all the crust away, it's not a stretch to say said "scorching" would be melting- alternate methods like fragmentation don't fit that boot. I also think there's also logistical problems with the current calc that make it too much of a lowball to be useable, but more on that there.
Let me know if my added reasoning is satisfactory or if you have any further questions.
