Let's us a simple example: fireball. Here's the SRD entry:
Fireball – 5th Edition SRD
That is too wordy on its face. The lines giving range and stuff are fine, but why not an "Area: 20ft radius sphere" line and an "Effect: 8d6 fire damage" line? Then it is done.
Lots of spells, class abilities and other bits are like that: completely unnecessary prose.
But, to be clear, I am not just talking about trimming prose. I am talking about using visual design elements like one look maps to increase utility.
