I'm sorry there is no evidence that a particular language is 'better' than any other.
All human languages have very similar every day vocabularies - English happens (now) to have a very large specialist vocabulary (which wasn't available to Shakespeare) and which it actually shares with most other languages.
Shakespeare got his vocab up by generating a host of new English words from French, Latin and the other dominant languages of the time.
As we speak the Kiyuku Shakespeare is stealing words for his play.
> the nuance of the finer English texts could be adequately captured in Hieroglyphics
On a technical point you could copy Shakespeare into it now - it has (most) of the current English sounds and with a couple of conventions/accents you would be good to go. I wouldn't recommend switching writing systems anytime soon.
