DLC Character Types?

I was looking at the website yesterday and I saw there was a chart that explained how the roster was broken into character types and ranked by difficulty based on the type. There wasn't any mention of DLC which led me to think that the chart was outdated but it's still interesting that there was a classification system.

If this chart were to be updated today, where would you guys place the DLC characters (Spectre, Brawler, Battle Mage, Monk, Nen Master)?

UPDATE:

The answer is actually on the website! It's on the Fighters page.

An outdated classification system from the official website.
