I’m currently struggling with deciding who my second main DPS in Genshin Impact should be.

I already have some characters built, but I’m not sure which DPS would actually fit my team best in the long run. I already have Arlecchino she is basically my main DPS together with Bennett, Xingqui and Succrose.

I’m also questioning whether I even need to focus on a second main DPS right now — for example someone like Neuvillette or if it would make more sense to fully build my team around Arlecchino first and really invest into her supports and synergy. What about the upcoming ones like Columbina or Ineffa?

Basically, I’m torn between pulling for another main DPS or optimizing what I already have. Any advice or personal experiences would be appreciated.
Should I aim for Neuvilette or someone else?
