I find this an ironic statement considering you are implying that the most valued player should not be obtainable from the losing team. You’re essentially saying that it doesn’t matter how good you play - if you lose, sucks to be you, even if you outperformed your opponents for 90% of a game until the late-game turnaround.
You will not reinforce constructive contributions if you want to shine a flash-light on a given team. This incentivizes nothing other than “It’s OK, we won”. The way it is NOW highlights those who broke the normal barriers regardless of whether they won or lost. This is better. You don’t HAVE to win for the game to say “Hey, you did X amount better than your last performance/other people - and happened to be top [insert medal here]!”
Or you could just press TAB (stat-screen) and check both teams out without the medals and padding, like everyone else does. If medals and MVP means little to anyone, they can skip ahead and get back into their next queue within a few seconds of game-over.
As for people stat-farming, that sort of drivel primarily happens in QM or AI modes. You won’t find much stat-padding in ranked unless someone is stupid enough to quote their stats thinking it absolves them of a criticism, like “Hey, I have more kills than you, so why are you flaming me for my 11 deaths?”
Kills by themselves don’t mean much from the MVP perspective unless they also contributed something else in a meaningful way – and much LESS so if they themselves are dying frequently. If one guy got the last hit on 25 heroes but had barely any hero-damage, siege-damage, damage taken, shielding/healing or XP contribution, there is barely any chance of them being put on a pedestal - same applies to heroes who focus on hogging a particular stat, such as siege-damage. Even if they were doing OK in other fields, frequent deaths would sully their statistics. If someone IS netting lots of kills/assists and ISN’T dying frequently and IS contributing to other statistics however they can, then they have every right to be considered an MVP, winner or loser.
There have been COUNTLESS games where, as a support main who tends to get very few (often no) killing blows (but a wealth of assists) in-between fulfilling my primary function and avoiding death as much as humanly possible, it is no surprise when I get MVP over others, even in games where someone has collected up to (or beyond) 15 kills and various other stats - because I’m also doing hero, siege and XP contributions as well as my usual healing, and making a huge effort to die as little as possible >> which is one of THE most important parts.
Lately my KDA has spiked up after countless games with scores like 0-18-0 and usually top (or close to top) healing. Why wouldn’t that get some recognition, even if I lost? There should be no surprise when someone does this and gets MVP, even if they aren’t topping damage, siege, XP, tanking, or actual kills. The game rewards participation.
Nobody will tell you the statistics feature is perfect, but it seems to me that a lot of people who complain about it have really high self-expectations or are playing in a way that doesn’t get them rewarded often enough for them to think it’s right.
