this implies that a person who doesn't form a group doesn't not have this knowledge... which is wrong.
maybe. or it maybe it demonstrates that the people forming the group understand that they will most likely be paired against 3 opponents who will be randomly paired together and who have less of a chance of winning because they will most likely not be able to prepare against a team that has played several matches together. which would mean that it actually demonstrates that you are skilled in exploiting potential weakness in the games ability to properly determine skill at the actual game from a competitive standpoint.
i'm not exactly sure what blame has to do with anything...
this isn't a socialization simulation game. your ability to socialize isn't taken into account when your rating is determined. the game doesn't scan your chat logs to assess how well you socialized. you can win without communication period. in fact, if you beat a premade team as a solo que team, without typing or speaking a single word, albeit rare, it actually would demonstrate more skill. you assume that people who don't wish to form a group, or don't have time to do so, do not possess effective social skills or the ability to plan...
uhhh no but ok.
other games of this type with competitive pvp modes take into account that allowing premade groups to compete against solo que is not a fair way to rate skill.
plenty of people agree with me. just look at the thread topics in the pvp section... and the people who disagree with my point of view can only garner weak arguments like "but muh frens" and "why can't u talk gud enuff wit ppl 2 win".
