She shreds Geo so it helps to have a geo main dps. The thing about lunar crystal is that you need to apply geo on water which is actually possible with lunar chrystalize because you keep hydro+electro but might not be possible with lauma as dendro soaks up the hydro. Need to see tests first.
The current stygian has the duck and i can't kill on fearless even with ineffa+bina and it's hitting me again how useless and bad this endgame is, so i'll probably skip linnea because i don't want zibai and i find reaction locks annoying. I won't clear the geo gecko by any means but i don't mind 1 less dust feather per patch or 100 less gems per month.
Either way, in the end it depends how much you like the unit really and how much you care about meta, cause there is no point rolling a unit to never using them. If you want to play meta, then Linnea is made for zibai but so far looks good enough even without zibai, can probably deal with wild hunt and herra with columbina. If you want to explore, being forced into hydro kinda sucks but she can heal, mine, capture animals and most people have furina.
afaik she's actually, surprisingly, not locked to 2 nodkrai as her enhanced passive only increases her geo shred from 15 to 30%. In that case she uses the husk set.
