im confident in my english, i think i might even be C1 or C2 (never took the test)
speaking however is out of question since i almost never speak it irl (there's no one to speak to)

erm it does though, in a way
you can learn a lot more, read a ton of translated books, speak with people from other countries, learn their culture, have a better idea on how varied the world is etc etc
basically it opens more opportunities for you
