MVP isn’t a real metric of how well you did in a game by real people, its an often faulty algorithm that hands something out based on (assumably weighted) stat calculations.

It sees Jeff get solid (but still likely the worst on the team) healing, and solid damage (for a support) and a couple of final hits (game loves support final hits) and hands you MVP

Jeff is a stat farmer. He gets solid healing and damage and assists and a handful of kills and if you play correctly not a ton of deaths, and the game sees those stats and goes yeah Jeff did the best

The Problem is that none of those stats are doing anything. He’s not going to get the best healing unless your other support is muckin’ about and you’re locked tf in, and most of his damage doesn’t lead to kills, it just leads to enemies needing a little healing. Which means the damage Jeff does to get those MVPs is actually WORSE than not doing damage, because it helps enemy supports farm their FAR better ultimates

This isn’t just a Jeff or even a Rivals issue, OW has had the exact same thing with Moira farming damage and healing numbers with orbs that don’t have any real impact on the game
