I'm not sure what your point is. I'm talking about how to stack the odds in your favor, utilize limited resources in an optimal manner, and put together a balanced team given a typical set of starting conditions (e.g., one SSR of the element you're interested in). Saving up your Gatcha rolls for a rate up is one way of stacking the odds in your favor, and to do this you have to pick a time point to roll the dice. That means you have to pick an element and you have to pick a kamihime to bet on. If you don't do this you aren't using your jewels effectively.
