While Fraymotifs are very much, as you've said, complex and hard to accurately theorize about, with (seemingly) up to 12 people able to join into a single Fraymotif as long as its 12 different aspect-bound and there being no apparent limiters to even cross-session combos, its so interesting to hear talk of them at all anymore since overall we saw so little of this mechanic in action throughout homestuck's narrative. Any particular potential fraymotif comboes you'd be interested in seeing happen?
Oh yes it’s definitely a super cool mechanic, and I also love the way they are named and would LOVE to see what Hussie has to say about them! Fraymotifs and Denizens are two of the things I wish Hussie talked more about post-canon.
As for Fraymotifs I’d enjoy? No specific combo of two pops to mind, but I would like to see like, a full 12-Player Aspect Combo Fraymotif, like what EVEN would it be combining every single Aspect into an attack?
