Don’t get me wrong, I’m not being mean, I don’t want to tell “you are as bad as one-tricks”, my point is that – again, unless bronze – the one-trick played many-many games and won more than half of them, otherwise he’d still be in bronze. If all those previous teams could win with him on it, it’s objectively not true that he is throwing. He did the exact same thing in the last 100 games and won 50+, there is no reason to expect him to do any worse this time!
If one-tricking is bad, then one-tricks would all be in bronze, while one famous one-trick got into top 500 with Symmetra … and got banned for being disruptive after so many reports by people who “carried him” to his 63% winrate. In competitive games, the results speak. If someone is bad for any reason, including bad picks, he’ll lose and end up in low rating. If someone is not ending up in low rating, maybe he didn’t do bad picks.
I think the solution is a serious delusion in the Overwatch community: that this is a team game. Well, it’s true for real teams that actually practice together and have a boss making calls. But for random games where people can’t even be arsed to wait for the others to die and res (not to mention retreat when half of the team is dead) but run in alone 1v6, team comp doesn’t matter. If I got a rating point every time the damn Reinhardt switched off his shield when 3 enemies were aiming at me, I’d be #1. Now I avoid the shield, making the Reinhardt (even the rare ones who can play) practically useless and pray every game for Orisa + D.Va (but for no avail, I almost always get that damn thing).
The truth is that Overwatch is no more a team game than a random battleground in World of Warcraft. League of Legends did it much better by defining roles and fitting champions. A Nunu mid or Ashe top are reportable for trollpick. Also, LoL has lanes with roles, a Morgana supp (OK pick) going second mid is also reportable. But there are no roles or lanes in Overwatch, just a mess. In this mess the only thing matters is how well you play your champion and this is why a one-trick shines. Someone with 100+ hours will likely defeat his hard counter who has 58 minutes and picked because “the team needs him to counter X”. (if I got a rating point for every Genji I killed with Bastion…)
You have to see that the “one-trick” problem is only in your mind. If it was a real problem, it wouldn’t be your problem, it would be Bronze problem. Your problem is the wrong belief is that you are “forced to fix” something they broke, like “duo instalocked Hanzo+Widow and now the rest of the team had to pick tanks and healers”. You need to wonder how could these Hanzo+Widow get out of Bronze? Did they always get 4 friendly players who could play tanks and healers? No, they usually played with a Reinhardt (there is always one of those damn things), a Moira/Mercy and 2 other DPS and won more than half of the time. Your problem is your own making, you throw the game by picking a role you can’t play to “fix” the team instead of just playing what you can. If you hava stable of offense champions, you shouldn’t pick Reinhardt after a Hanzo+Widow instalock, you should go after the enemy tanks as Reaper knowing that your usual counters will be headshotted.
Let me tell you a fun story. I picked Bastion on Temple attack, which is “throwing”, so the team decided to teach me a lesson: they switched to Widow, Ana, Symmetra, Hanzo and Torb to show how horrible it is to not pick the “right” heroes. They were throwing laughs on chat while the countdown went and discussed how this horrible defeat will teach me to be flexible. Through the door we could see a Junkrat on the big rock throwing his bombs at the entrance to farm some ulti. I doubt if he had time to realize Widow+Ana+Hanzo before he died because the door wasn’t even fully open. Pharah ended 3 seconds later. D.Va was also forward so I deployed sentry and she was watching death recap soon after. Then we ran up, there was Reinhardt (there is always one of those) who could either face his shield at me or Torb+Symm behind him. He finally choose to charge but his health disappeared during the dash, leaving them with a Mercy and a Moira with the expected result. They spent the rest of the game typing instead of playing, mostly telling us who should be reported for losing.
Finally let me have a suggestion: “one/two-trick queue”. In this you can only play with your top 2 play time heroes and your team are other one/two tricks but never players who have the same top play time hero (so if you have 80% Symmetra play, you will never get a Symm main teammate). Such teams would participate in the ranked games normally. This can even be enforced, if you have 60%+ play time with one hero, you must either queue one/two-trick, or if you queue normal, you must not pick the 60%+ hero. There would be no more flaming, an attack Torb has no reason to say a word to attack Symm, while flex players would never see another one-trick on their team, reaching perfect harmony forever!
Oh wait, there would be flaming, because the one-trick teams would massacre the flex teams and they would go to the forums how overpowered it is and now they are “forced” to pick a main and queue as one-trick also but that’s not fun.
