So, after going through this subreddit for some time, I sort of realized that many people disagree on what the correct way to build Yelan is. Some say that HP & ER > Crit, whereas others say ER & Crit > HP since you can just use hydro resonance.

Having said this, I’m not sure if I should use Fav bow instead of her weapon (Aqua) due to the differences in HP & ER. With Aqua, I have to sacrifice CV & HP value to hit 182% Energy Recharge, leaving my Yelan at around 68:200 with 33k HP (no resonance).

Fav bow fixes her ER issues, which then lets me build more HP and CV, ending at around 35k HP, 190% ER, & 70:190 CV (no resonances/team buffs).

As such, in you guy's opinion, should I use Fav bow or Aqua Simulacra? And is HP more valuable than CV?

Thank you in advance for any replies! Both builds use the 4pc of Emblem of Severed Fates with HP/Hydro/Crit Rate pieces.
