It is strange to me and maybe you can give a reasonable explanation why every streamer is bashing that numbers became bigger. Every expansion they were getting bigger and bigger. And if you dislike bigger number you can select % display.
I personally doesn't see a difference between having 22000 hp or 22000000 hp. It is just a number and anyway we will hve to switch and adjust to seeing different numbers.
What is the good reasoning against big numbers ? But please don't use "natural" example as this is not a legit reasoning.
