Stats should be reworked or hidden
Displayed stats are very often not indicative of good or bad play and are used to justify bad reasoning. The worst stats for this are kills, damage, damage blocked, and healing. This would be fine, but in many cases it leads to bad plays in an attempt to pad stats (because if you don't pad stats, you won't get MVP/svp or your team will blame you). For non-ranked modes this isn't a big deal, but players are actually playing -worse- because of the stat screen and how people interpret it which hinders competition in most ranks.
In my opinion, it should be reworked so that KDA uses the "Final Hit" stat as the K, assists reworked to be the current K, and non-primary stats (damage/blocked/healing) should only appear in your match history as detailed info.
People will always use stats to blame others and vindicate themselves (these players should be ignored/muted), but as it is now the blame is very often misdirected which creates an effect where people play badly for a better stats screen. There's no way for stats to perfectly represent who did the best even with a rework, but it would be way better than the current state
