Not using WAVE or some kind of accessibility checking can make your website vulnerable to law suits
WAVE makes it easy to find and fix the easy stuff on your website
avoiding obvious violations that might prompt a lawsuit
such as no alternative text for screen readers on images
Following principles of Universal Design for Learning (UDL) helps ALL your students have better access to your content
I use WAVE as a minimum standard for our library website and for vendor products.
I keep my notes on Universal Design for Learning (UDL) at https://library.fvtc.edu/UDL
