Doing 25-30k per tick how can I improve?

I have Neuv c1r1

Team is sucrose on VV, Fischl and Barbara.

I don't have Furina, Xilo, Ororon or Kazuha and I dont like anyway use everyone else's team.

Cr is 60% and Cr damage is 220%.

Would maybe kachina on natlan set be better than sucrose on VV?

It doesnt make much sense since kazuha is just a better sucrose but who knows.

More crit damage would be nice but I feel farming artifacts just boring and totally random. I could farm for 6 months and never get a better piece.

What would you do?

Thanks
