Tholei think going off gut instinct for a lot of this shit is part of what makes tf2 so much better than its peers. tons of crucial information is not really just given to you 24/7. better players will have better gut instinct when it comes to uber ad/disad, enemy health, how many stickies your demo has loaded, etc. all part of the charm and skill ceiling.
Fair, but when things like match hud, player outlines and heal target's ammo count were added to the game, they were seen as welcome quality of life updates, and not as some crutches for bad players. Medics have been using chat binds with uber info for years, and this uber on hud thing kind of accomplishes the same thing.
I agree that using your "gut feeling" to anticipate enemy health and ubers is a part of the game's skill ceiling, but I don't think that in a serious comp setting people should ever rely on this feeling to figure out what their medic's uber is. Making a call that you have uber once you get it doesn't exactly take a lot of game mastery either, and to me it seems more like busywork, rather than good game sense.
