You must have a very loose definition of the word “facts” if you think anything you’ve typed leads anyone to conclude a zeta shortage is due to Kyber squish.
“Unshakeable image” is a poor argument too… just because I think something is doesn’t make it so.
Believe what you want, the real facts are what OP and the rest of us care about.
TLDR; yes new characters do need more zeta mats to perform at their best. That doesn’t mean you should slap zeta mats on every new character. Stick to your farms, and if you do find yourself to be short on zetas chances are you are farming too much too fast.
