The "hit box" is the invisible clickable area around a player or NPC that can be clicked to target the player or NPC. A mob with a larger hit box is easier to target because it takes up a larger part of the world and is easier to click.

Because it is typically in the best interest of the player to be as difficult to target as possible, smaller characters would be a preferred choice if hit boxes were not somehow normalized as they are in most games, either by creating them equal-sized or including something normal like a nameplate as a part of the hit box.

In TOR, the difference between the smaller and larger hit boxes for players is somewhere between 175 and 200%, and are not normalized in Warzones or anywhere else. Making the poor fat dudes in some cases twice as easy to target as a female character or Type 1 male. And I've found myself click-targeting a lot more because the tab-targeting system has some issues of its own.

In short, for the sake of the fatties, please make nameplates clickable.
