Meh, it's all a waste for the most part for me. I get others don't agree. But then I'm on team "tiny combat blocks" so I get it.The fact that it has utility for the other 10% makes it worth including, since it doesn’t take up any more page space than ability scores were already taking up anyway. In fact, this formatting takes up less page space for monsters that have save proficiencies than the 2014 standard of having an extra line for save proficiencies did.
