I don't really think they can do that, since the damage of rend is still got to go through the targets armor so it'll be hard to make it where it'll show you when it can kill a target. Since your target can have either no armor, or might have a few hundred, it would be hard to make the game calculate that with the rends damage in the health bar.
Champions like
can have that indicator because Cho's is true damage and Pyke's is an actual execute like I believe
was and had an indicator which is also true damage on them.
^ exactly this.
For example, Veigar does not have an execute bar for his ultimate. Neither does Kayle, neither does Akali.... etc. The reason for this is because it could give a "false positive". It may say that it will kill, but due to it being effected by many things including shields, resists, and damage reduction like with Garen... it would be very wonky for sure.
Another good example is Garen. Although it is an execute as well, it is effected by other factors like Shields, and magic resist unless they are the villan. Same as Darius, shields can stop him from killing and if vs Trundle for example.... his damage with ultimate can be lowered by Trundle's Q which reduces Darius's attack which reduces the damage Darius's ultimate does.
So while there are other executes, the rule of thumb is if it is able to be denied with a shield, it will not have an indicator. (Chogath is included in the no indicator.)
