Why personal performance is bad and broken:
First of all, personal performance does not work properly. I’ve had games where I was objectively doing very well, getting gold elims/hero damage/ obj time and very high stats for both. I was doing absolute work on the enemy team. I would sometimes still lose 25 rating. I know I know “then you weren’t playing as well as you thought you were” ok maybe a few times you might be correct but I can honestly say without a doubt there were times where I was truly objectively playing very very well and getting the gold medals I listed above and doing some real work on the enemy team yet my team couldn’t capitalize on our hero advantage and we would lose. I would still lose 25 rating.
Then I would have games where I was doing poorly and performed maybe 25% as well as those other times I listed above. I would still lose 25 rating. Now there are other times where It does not dock me as much for a win or loss based on my performance but there are definitely times where I perform incredibly well and still lose 25 rating. Then In the next game I would play absolutely amazing and our team was good and we would win and I would gain say 17 or so rating. This cycle would repeat some days and I would actually lose rating with a higher than 50% win rate. Something is not working properly. On to my next point.
Personal performance supposedly helps those who are good and get punished by being on bad teams with bad players. Removing it would benefit those same players as they would be gaining more on average per win in the long run. I think it is imperative to remove at the lower ranks as it makes it very hard to climb sometimes when you are constantly paired with poor teammates, people who purposefully throw because they didn’t get the hero they wanted, or people who just leave games out of anger. Then you do incredibly well in a game and still lose an absurd amount of rating. Or you do incredibly well in a win and gain only a percentage of that same rating then it keeps on repeating and you climb at a snails pace.
Blizzard I highly urge you to remove personal performance in all brackets. I think it would be better for competitive in the long run.
