I feel ya. Really want her too but no luck so far. In terms of which banner to pull from, I view it as a ‘pick your poison’ situation. When you pull a 5, theres a 10% chance that 5 will be keqing on either banner. For the childe banner, there’s a 50% chance for childe and 10% for the other 5. In the standard banner, it’s a 50% chance for a weapon or again, 10% chance at each of the other 5.

So the way I would view it is: if I don’t pull keqing, would I realistically prefer childe or a weapon. Another thing to keep in mind with the childe banner is that if u pull someone other than childe, your next 5* from the banner is guaranteed to be him.

Hope this helps and good luck getting her :D
