However the argument is fundamentally wrong. Why? Because “one-tricking” which means playing one champion can only be defined over multiple matches while you play only one game with one particular team. They surely don’t care what you were playing in your other games. They want you to play something else in this game. They don’t report for your picks in other games, they report you for your pick in this game, regardless of what you usually play.
The point is that “don’t one-trick” actually means “always do as the others tell you to do”. They believe that if you just pick against their will once, you reportable. Sure, if you do it just once, you just get one set of reports, but you see the problem.
But who is this magical “team”? Who has the authority to tell what to play? The “team comp” you don’t fit in is created by other people’s arbitrary choices. They practically say “I picked a sniper, so you must not pick another sniper”. But why I should change, why not you? Just because your computer loaded faster? This is true for all “not fitting” problems. Let’s say champion X and Y has no synergy but X and Z has (for example X can use a shield tank) and then “the team” says you must pick Z instead of Y. But why you should change, why not the other guy?! Especially when the other guy has multiple golds and the whiner has zero.
There is a thing called “meta”, the champions that people usually play and got used to play with. This creates a sort-of-consensus among the “team”. If we accept that one must follow the consensus, then one must always play the meta. If he deviates once, it’s reportable. Which is especially problematic if the meta is wrong, like 2-2-2 in bronze-silver where people insta-die due to mistakes, without the healers being able to do anything, so the 2 healers are just doing bad DPS. Seriously, if you have a troll account, try to play Mercy in bronze. You’ll be shooting with your secondary 90% of the time (and learn that Mercy ult is for countering Pharah and ninjaing objective). One healer would be much better, “but meta”.
So we reached full circle and can translate “don’t one-trick” into “always play the meta”! You see now what’s the problem with that, right?
Finally, one can ask why not Blizzard intervene and create a champion selection system like it’s in League of Legends? Make 2-2-2 official if they wish and make people queue with their role requests. Apply bans for champions before pick phase. There are 28 I guess and as both teams can pick the same hero (unlike LoL), having 2×6 bans wouldn’t make the game unplayable, especially if the bans are blind. A commenter said it perfectly:
What Blizz wants this game to be is a fun interactive game where people all work together, but also get to play their favourite heroes. You unfortunately cannot have it both ways Blizzard. Either people work together based on structured rules on who should play what at what times, or you just tell people to play whatever the hell they want and stop saying “but you need to switch to help the team”. Right now it’s a shit show, and not even Blizz can stay consistent on what they want to say.
PS: I must quote the best comment: “Finally, someone at Blizzard agrees that other bastard should switch!”
