You're naive as hell if you think solo players don't use teamwork. Don't stick to Riot's word's so blindly; they have a well known reputation of lying. Regardless of of whether you're solo or premade, people who use teamwork willl use teamwork and people who don't won't. If you're the kind of person who sees 4 squishies on your team and then chooses another squishy, you're still that type of person in a premade. If you're the kind of adc who is against Vlad, Swain, and Warwick and doesn't buy mortal reminder, you're still that kind of person in a premade. The difference between premades and solo players isn't teamwork like Riot wants to claim in order to force this down our throats. The difference is the ability to make on the call high coordination manuevers. Premades can immediately react to a gank bot with a double teleport from mid and top. Premades can immediately coordinate a chase into a flank and pinch maneuver. Premades can do an instant global ult combination from however many players.
And it's because premades can execute this on the call highly complex maneuvers that they will generally have more of an effect on the game than any solo player. Which means that most games will be determined by which team has the better premade. A variable that's completely random to solo players. The solo player's efforts are commonly uninfluential unless they're the cause of a loss. Solo players really only determine the outcome of a game when the premades on both sides are evenly matched which doesn't happen often. And so a solo player's luck has been unjustly important in winning ranked games.
And that's just the general case scenario. I didn't even mention that situations you would have to be absolutely close minded as hell to ignore. Riot has stated that it's a 1/1000 chance that premades get matched up against all solo players. That statistic isn't that scary on its own, but you have to understand that's just the worst case scenario. That means that chances of larger premades getting matched up against smaller premades isn't as rare as you might hope if the worst case scenario is only 1/1000. And guess who gets screwed over hardest in cases of premades with different sizes? I'll give you a hint: a 4 premade vs 3 premade will have 1 solo on the 4 man team and twice as many on the 3 man team which stands a very significant chance of losing. The game is statistically stacked against solo players. You have to be completely close minded to ignore the math.
