You can make an argument that score boards would be toxic, but I think it’s actually more toxic because as a healer, I frequently get attacked for not healing enough. And yeah, gold medals don’t matter, but I think when Zenyatta is out-healing Moira, there’s a huge problem.
The team is right to complain about not getting enough heals, but I think if they were able to hit tab and see the raw numbers, instead of cursing me out, they would ask Moira what the hell she is doing?
Also from another standpoint, when my team is failing really hard, I would like to be able to look at the scoreboard and see what is happening. In the current iteration of the game, I see people blaming DPS the entire game, and then once the game is over, we see the scorecards and realize that our Symmetra was actually carrying with damage, but we had no way of knowing it and she just spent the last 15 minutes being harassed for playing a non-traditional damage character.
It would also make it easier to identify who the biggest threat on the enemy team is. Are we losing because no one is handling Tracer? Is it because their Reinhardt is getting a lot of kills? Are we ignoring a Zenyatta in the background?
It would also give me an idea of what I need to improve on. Are enemy healers significantly out-healing me every single game? Do I need to focus on healing more? DPS’ing more? Better objective time? etc.
I just don’t see how this would make the game worse to play. The same system actually already exists in pretty much every competitive game I play currently. Even in Starcraft 2 I’ve made the biggest adjustments in my game-play by looking at the score screen after the game was over and being forced to realize that the other Zerg players were out-performing in every way imaginable.
