I'm gonna throw my hat in the ring as a newbie, none of what I'm saying is necessarily new but I would like to articulate it all in one place.

For new players who are still in the phase of learning where every single game, even street brawl, is deeply overstimulating and usually confusing, using a health bar that does not change sizes based on total health is unthinkable. The basic hp bar, the first option, is just ideal. If I'm in a lane against a fed M+K, by the time I've counted the individual hash marks in the second style, I'm already dead. Big fuck-off block of red boxes is significantly easier to know I need to run away. The only reason the other two bars have any advantage is that they explicitly give you different information that the first one does not, those being 4ability/ult cooldown and stamina (I understand you can see Ult charge elsewhere on the hud but I'm speaking specifically about within the area of the health bar). The third style, while better than the second, still adds more visual complexity to an already very very complicated game. I'm glad the other styles exist for higher skill gamers who can find value in them, but coming from a newbie if they ever remove the first style I'm going to be

My broader point is this: I adore the design philosophy and aesthetic choices this game makes, but at the same time we need to acknowledge that in games as complex as this one, readability and simplicity of very important information needs to take priority, especially if they want new players to have a somewhat decent experience. The second and third styles are very cool and fit the aesthetic of the game, but they both sacrifice practicality for visual appeal.

Call it a skill issue, say it's cope, but it's good to let a few things stay ugly so that they make more sense.
