Despite what people will say, it is nearly impossible to carry afterward because your opponents will:
1.) Have more gold
2.) Have more CS
3.) Have more of your tower
That is why it is completely acceptable for me to ask my team to FF once a mistake is made because as Vladimir, I cannot make a comeback as a late game champion. We should be open to the possibilities of predetermined victories and defeats and not make an unwinnable game seem winnable by wasting away time. Also, players need to stop asking for reports when I know for certain the game is lost and usually is, when it only takes 10 more minutes for the nexus to go off.
