Xianyun C0 vs C2

I've had and used Xianyun C0 in the MOC pretty frequently. I like that she makes Xiao, Furina, FaraC6 comp work, and like that I can turn units like Navia and Diluc now into hop'n'bop units.

I've heard C2 is a great Con, but as someone who has only gotten a single limited to C1 in 5 years of playing, I'm doubtful how much stronger C2 might make my characters feel. For example, I had Ruan Mei for half a year in HSR, got her E1 con and.... I literally can't *feel* a difference. But a different support, Tribbie, I got her E1, and it's so clear and obvious the impact her E1 has on my teams and how to utilize it, while also changing how I might play a fight, rather than being a strict damage increase.

So for those with Xianyun C2: how do you genuinely feel the benefit of having C2? Does it enable characters you know would haven't worked without C2? Or is does it mainly make the MOC a bit more comfy?
