80% of games are coin flips. When more than one member of your team is tilted, its very very easy for them just to feed kills and not know why. These losses feel like crap because there's not even a struggle. They are at your base before 20th minute. The reverse is the same. Enemy team has a tilted adc. You all of a sudden have a 5/1 Cait and she steamrolls the entire enemy team.
These games feel like a complete waste of time. I'd rather play the remaining 20% and make them count, with the rest just decided on a coin flip. The results would likely be identical.
