.... whats the point ?
Paying for 6* I get, paying for 5* of its the Waifu I get.
But paying just to pad out another worthless bench place ?

If you go this far, you are pretty much completely throwing out the gambling element, and the thrill and rush that comes together with it when you succeed.
At such a point the paid gacha becomes nothing more than everyday shopping for groceries, and the Game becomes just a stamp collection.

I am in no position to tell people what to do with their money, but just pause for a second and give a thought to what I wrote.
