Discord really went from 32 unicode characters + 9999 discriminators (32,000 printable unicode so 32,000^32x9999 = actually incalculable on a lot of calculators, essentially infinite) to presumably 32 english alphabet characters, periods and underscores
And at the same time alienated anyone and everyone who doesn't speak a language using a latin alphabet (most languages) - and languages that don't use the english character set (basically all of them) - made stalking easier, removed individuality, and destroyed their actually revolutionary username behavior
...to look like twitter.
EDIT: as pointed out, it would be 32,000^32 (32 characters, 32,000 variations) rather than 32,000 characters with 32 variations. that number is still incalculable by a lot of calculators, but it's a significant difference! here's the actual count (as it's thousands of zeroes less)
146,135,548,716,716,982,791,186,446,423,301,139,135,396,694,972,170,240,000,000,000,000,000,000,000,000,000,000,000,000,000,000,000,000,00,000,000,000,000,000,000,000,000,000,000,000,000,000,000,000
