List some of your "there's no solution" scenarios
For instance, you fall far behind the enemy Varus as Ashe, try to farm on your side of the map, but will constantly get tower-dived even if you hug the inner turrets. Fall back? Vi chases you through it and ults you to death. Call for help? Your teammates are premades who got mad at you for "feeding" (even if it was just the enemy jungler camping you a lot) and insist on you being the scapegoat, so they're only going to help out the enemy get to you. Farm in jungle? It's already been conquered by the enemy. Surrender? 1/4 premade veto.
And remember, the above is the typical 9 vs. 1 situation. There's no playing without getting royally fucked over by EVERYONE in the game. Even leaving will just dig a deeper grave.
Bottom line: No solution. You're already fucked just by having queued up.
