Macros in XI HELPED with DPS because they allowed for you to gear swap. It is also the only way to keybind abilities, so if you don't have an ability macroed you have to navigate the menus to trigger it. XIV puts all your abilities right in front of you in a clickable and bindable fashion and has no gear swapping. Even XI had the /wait limitations but you couldn't always manually trigger abilities that fast anyways due to long cast times or needing to jump to a different menu.
