The sentiment of not wasting time trying for anything less than a B2 across the board is right on the money, in my opinion. However, B2 being a joke is a stretch. If we're gauging by CEFR levels, B2 is where it gets "interesting"; sure, you're not a master of the language and WILL screw the subjunctive up, as part of the experience, but you're able to hold any, if not most, conversations that aren't overly technical. Same with consuming material in said language. What you're describing is closer to an A2 with a meek personality.
That being said, B2 is a worthy goal to pursue! It was when the language started getting "interesting" for me. You're learning all the time, while using it.
Something to consider: The amount of vocabulary words that you must know per level doubles, as you go on:
B1 = 2,000 words.
B2 = 4,000 words.
C1 = 8,000 words.
C2 = 10,000+ words.
i.e. upper levels take "more time" to learn, once the basics are down.
