This just doesn’t really apply to utility only but also performance, stats IS NOT everything, in fact you can play heroes and still have mediocre stats but performance lies more over your response and coordination to a point where you have a lot of good assists/kills or being completely deathless in the process while still do your jobs.
A lot of key elements and tactics do not have score board showcase due mostly being impossible to track (e.g. lane freezing is literally just watching minions die and stop the enemy from getting closer so your siege stats tank a little) which is somewhat disappointing.
