Pantheon QoL change

So, you probably know that Pantheon's e has got a passive that makes his autoattacks and q crit when an enemy has got less than 15% of their max hp. I think that it would be a good thing for game clarity if champions (or maybe even minions/monsters) had a visual notification for this. Like, I don't know, a spear icon above their head (much like zed's ult mark) when they have less than 15% hp. It would help both Pantheon players and Pantheon enemies. Yeah, I hate when people complain "OMG THAT SPEAR DID MORE THAN 1000 DMG RITO PLS"
