Why doesn't Darius ult tooltip consider passive AD for maximum damage?

Knowing Riot code it'd probably result in spaghetti if they tried to get a tooltip to do that.

This is a bug going for half a year now, I made dozens of posts and tickets but Riot simply doesn't care :=)

Honestly, as a fellow dar main, this issue doesn't bother me much. Simple math generally gives you a good estimate, and since nobody has time to 100% accurately read an enemy hp bar during the thick of a close fight anyway, it seems to be of negligible impact anyway. I guess my point is, it would be nice for them to clean it up, but Riot has bigger fish to fry right now.

Also, as a side rant, i'm more concerned with darius's aging kit. It seems no matter how many of these buffs, he's just becoming less and less viable against competent players. True, there are some great players that make him work mildly well higher up the ladder, but you still almost never see darius in organized play. The more cc and mobility there is, the worse off he is. Pure numbers buffs don't help a lot (armor pen, q healing, W scaling). They mostly just help to stomp bad players. Against good opponents, it's still near impossible to live the darius juggernaut fantasy, as literally anybody and everybody can counter him well, since he's more of a mistake abuser than a proactive winner like yas, akali, any adc, most mages, renekton, etc.
