I would hate to see everyone lose their individuality in order to conform to rigid standards. Often what is lacking in vocabulary is more than made up in other attributes and a TCer's personality.
I would prescribe practice, lots of tasting and taking notes that can form the basis of a review later.
A place like TC is a great place to learn ... like for 5 years before TC, I had no idea how to describe the differences in astringency and bitter. Umami, grassy, veggie, etc.
But the best part, practice is so enjoyable when it comes to tasting tea.
