You missed his C2, he also gives 12% anemo shred on skill use. So its 32% (only 8% less and more reliable), and 20% attack if you have his Elegy bow. Not as good but still a fine support! Besides, he's useful outside of being a walking damage-buffer . And cute > meta!
Also some people have awful 4star luck so the C6 CD buff for Faruzan might be hard to get. >>3763266
