True Stealth even more broken than Pure Damage

If anyone remembers waaay back when challenging smite was released, it was accidentally coded to deal Pure damage instead of True damage. What's Pure damage? It's what the fountain (and only the fountain) deals which allows it to ignore all revive and invulnerable effects.

It was absolutely hilarious for one particular reason. Tryndamere was a pretty popular pick at the time. So we saw a lot of them dying to it. Almost as funny as when Tryndamere could team-kill.

Of course, that was a bug. And was fixed even despite only effecting a small pool of champions, only 6 effects in the game total. But somehow one champion is allowed to have True Stealth, which makes them untargetable for the vast majority of damaging effects in the game even if you have vision. How does that sound reasonable?

It seems like someone was having flashbacks to when Pink wards completely destroyed any attempt at stealth, but didn't think about the effects such a thing would have in a game where Pink wards no longer exist.
