Okay you clearly aren’t understanding it so I say it much MUCH more explainable.
Okay if you pick one hero and continue to only play them all the time and not other heroes that you can play as well , this the only person to blame in this situation that you can’t swap without throwing is you.
YOU qued up for the game , YOU one ticked, and YOU can’t switch.
Noticing a pattern the problem is YOU not that they are better not that the enemy team just picked better, it is because YOU one tricked, they countered YOU and they whiped YOUR team because of this. now it’s not just you at times some times there are whole teams of one tricks but it doesn’t erase the fact YOU are at fault too.
