I'm not as smart as other but hopefully this help you understand.

If you already have such thought then you should already understand, the reason is balancing purpose. Let's use simple math for two SSR Rulers AOE Buster by their Buster attack.

Amakusa ATK is 10972, Artoria is 9593.

Amakusa have 30% Buster Up with him so roughly 14623 for three turns.

Artoria have 70% Attack Up, split into 30% for three turns and 40% for one turn. Roughly 16308 for one turn and 12470 for two turns. By average its 13749.

Both around 14k. If you add Artoria OCs and her 50% critical damage she may scored higher damage, however Amakusa himself offers NP-regen and star-regen that by three turns he has better access compare to Artoria who risks herself with card shuffle.

If Artoria ATK is same 10972 as well its 14263 for two turns 18652 for one turn. Following that her average will be 15726 for three turns, 1k gap above Amakusa compare to before, not counting her 50% critical damage boost and OC yet.

Is this close enough to clue you're looking for?
