Yep. And the older you get the more you appreciate the keybinds. Also learning keybinds is a transferable skill. For example when playing New World I had similar abilities bound to the same keys I’d use in wow.
Honestly if you want to improve your performance, try some arena / skirmishes. Whatever flaws you have are immediately exposed in such a high pressure environment where there’s (almost) no one else to blame. You’ll learn your keybinds faster too.
