Teamplay around champs with executes

Since this is a team game, after all, I wonder if I could get Riot to consider allowing teammates to see execute thresholds?

For instance, when I try to play Pyke, I am the only one who can see the threshold for the Ult. This causes a problem that makes it so that there is not a way for teammates to play around that ability. I run into the constant problem of things like trying to predict the damage output of the team and wasting my ult because someone stops hitting the enemy champ right before they reach the execute threshold. Or alternately, they keep going to hard and fast and kill them first.

If this is to be a team game, shouldn't teams be able to work with abilities like this, so they can either:

A. Target the next enemy once they get someone below that threshold to more effectively output damage.

and/or

B. make sure they don't stop outputting damage too soon.

I just think allowing the whole team to see the threshold on abilities like this would really increase the chance for the team to play better around one another as a unit.
