1. If John is not time-traveling as Homestuck defines it, why should we then consider that definition as irrelevant? I think that it's important, when criticizing a story, to take the story at what it says and does rather than imposing an exterior framework onto it, which can limit your perception of the narrative.
2. I just think that arguing about what role is "most interesting" for Vriska to play within a story is pointless because, a) Homestuck seems very interested in characters (and especially Vriska) breaking out of the roles assigned to them by the narrative (see: Dave's struggle with being the "hero" of the narrative), and b) she is, unfortunately for some, the main character, and contains multitudes. On the subject of that particular scene with Rose, I think it's important to note that the context in which we encounter that scene is within a montage of the three-year meteor voyage. We don't have any real context for how Vriska has grown over the course of those years except for her character after arriving in the alpha session, which would seem to indicate that she's taken on a leadership/mediation role amongst the other characters.
3. So you think reading is boring? Very interesting.
