Yeah, I honestly don’t even know what the purpose of a HUD would be if it’s not to present that information to you in a useful way. If I’m having to read a tooltip to get the most basic information about a buff or debuff (i.e., is it a type that is dispellable by me), then someone has screwed the pooch in the design phase.
Now if only someone told Blizzard’s UI design team this 20 years ago, maybe we wouldn’t be in this mess in the first place.
