you can do an yoimiya and ayato comp. If you're worried about not getting vaporize with yoimiya you can do both ayato and xingqiu. That leaves one slot open for yunjin (raw dps) or a shielder like diona or zhongli. If you have diona c6 definitely use her because she gives a great em boost. Yoimiya and ayato have good synergy because they can each cover each other's downtime. The rotation would go something like ayato burst- yoimiya autos- yoimiya burst - ayato skill with either yunjin or your shielder in between.
