1. Efficient Use of Golden Soul Resources
It's not recommended to pull for both Ruan Mei and Luocha with Golden Soul resources.
Use them carefully as they are resources that cannot be obtained regularly.
Unlike Light Cone Shards, they can only be obtained after a character is fully duped (E6).
It's better to save them for future characters.
2. Advice for Casual Players
Since this game doesn't have competitive elements, there's no need to be tied to efficiency.
If you need them, it's okay to pull for Ruan Mei and Luocha.
However, you should avoid pulling unconditionally.
3. Thoughts on Luocha's Banner
Not recommended unless you simp for Luocha or want to collect characters.
His efficiency is low since there's an alternative like Gallagher.
You should consider the release of a hidden character in version 3.3.
4. Luocha Eidolon Efficiency Analysis
Luocha's eidolons are very inefficient.
Effects like 20% ATK increase are considered worthless.
It can even be a hindrance in a self-damage meta.
Luocha's Light Cone is valuable, but it's a different resource than Golden Souls.
5. Ruan Mei Banner Value Analysis
Not as essential as before, but still a good character.
Can be useful for players who started after version 2.4.
If your character pool is lacking, getting Ruan Mei E0 is okay.
To pull or not to pull is a personal choice.
6. Ruan Mei Eidolon Efficiency Analysis
Ruan Mei E1 (20% DEF Ignore) is still a good choice.
Worth considering if you're a Break Effect party main.
E2 shows an abnormal eidolon efficiency.
Not recommended to go for E6.
7. Final Summary
If you're pursuing extreme efficiency, save your Golden Souls.
Most people are against pulling for Luocha.
Getting Ruan Mei E0 is worth considering.
Consider E1 if you're a Break Effect party main.
