Is the Voynich illegible?

[Koen G]

I don't think fading and resolution are the worst problems regarding legibility. There are many pages where the text is crisp and easy to see. Of course fading is a problem if one's crib happens to be faded, but only a small percentage of words is faded to the extent that they become difficult to read. 
A much greater problem in my opinion is that certain characters exist on a continuum, notably a-o, s-r. This impacts both the reading of individual words as with fading, but also broader statistical analises.
