Oh wow you're so close to where I got stuck with Xav because I wasn't upgrading his cards anymore (lvl 70)!
The crit/crit dmg build is very good and useful but always remember that it depends on if you're stella matching and if you're up against enemies with shields. If you're getting enemies in weakened state (all shields down) then you're not going to do any crit damage no matter how high you get the stat, making dmg boost to weakened the most important stat together with whatever your companion is scaling on (atk, def, or hp).
If you're constantly brute forcing teams then yeah, you need to push for a good 70% crit or higher, with about 240% crit dmg.

But you can use every battle to test how well it's going and if you need more of one stat rather than another. What I often do is look up a youtube/tiktok/reddit/X video showing the build someone used to clear that specific orbit and then compare it to mine. Sometimes I can clear it with lower stats, other times I need to get very close to matching it. Either way you'll get a point of reference for the stats that seems to work (in case you decide to follow this method, never forget that the rank of the cards and their levels, together with a bit of companion affinity can skew the results and explain why you can't clear a certain orbit despite matching the stats).
