I'm torn about Drogon torching the throne, mostly because I'm not sure the degree to which dragons are meant to be intelligent. Are they just giant, firey dogs? If so, I find it hard to accept that he'd target the symbol of the throne instead of the guy who pretty obviously killed him mama.
Maybe I'm overthinking it, though, because I agree it was great to see the throne melt (even though they're basically rebuilding the same thing, minus bloodlines)
