Basically all primary tanks in game have a %hp ability, some deal a percentage of enemy hp and some deal a percentage of their own hp.

The few that don't have an alternate scaling that is still based off of their defenses and is a stat these champions are known for. E.g Malphite/Rammus with Armor or Galio with MR. The only two that are outside both of these are Cho and Alistar, and they're so old that it is probably just a kit age issue that they don't.

It is a stat to keep them relevant throughout the game. Without them you could basically just ignore tanks after they blow their cc because they have no offensive stats to be a threat.
