That's fair. It is hard to find a balance between building for units that have around 50% crit to rely entirely on CDom's buff, or moving to around 75+ so that they aren't useless when you don't run them with her. I have that problem with SBell right now. She does also have a lot of overlap with other single target DPS, and is why I haven't built units like Yufine at the moment.
One thing to note about Kitty is that her s2 gets in the way of autoing a little. I built mine in a tank build, so her s2 is useless unless it's specifically done to strip buffs, so it's fairly situational. But because the AI spams it as much as possible, that's a lot of loveliness S1s that I'm missing out on when I'm autoing with her. It's not a deal breaker by any means, but it is a hindrance.
