Trying to figure out where she shines, in regards to offense. The ticks/units seem too slow/low for her to be a pyro applicator to set up melt/vape for like Ayato or Ayaka's normals. And her damage is too low for her to be the one melting/vaping.

I've only seen speculation she might be used in Hu Tao, Dehya, and 2 hydro teams, but TBH that seems more like a "Where can Dehya even fit" as opposed to something Dehya makes great.

I like that her E circle is bigger than Bennett and most circles. Ganyu is like Albedo E size, yeah? It being that big, I imagine it wont need to be moved often. She has the free passive that adds 6 seconds on top of the duration after moving it. I imagine it'll become standard to E, then immediately E again and "move" it to just the same spot to make it 18s instead of 12s, with the 20s cooldown. c2 (sigh) adds another 6s when moved, which would make it above 100% uptime, 24s.
