As a Spanish, English, Portuguese and French speaker I completely agree, but I'd add there are too many sides in this issue.
I notice there's a context switch every time I switch language that destroys grammar and pronunciation. I get back to "cruise" proficiency in about 30 min to 1 hour. except for my native language.
I'd advise you to look for conversation with natives, as I've noticed I dumb down my pronunciation and expression due to the low English level of my coworkers, and every time I hit a Brit and have some beers it feels refreshing and like a different language.
