Faker played the worst, so why are people blaming Doran...

In Game 1, he abandoned his lane to roam bot, letting Orianna get too fed and causing the game to blow up.
Needless to say, in Game 3, he got picked off in a game that was on the verge of a comeback, handing it over.
In Game 4, while trying to go for armor penetration Akali during the Voidgrubs fight, he dumped his full combo into the grubs and ruined the game.
Oner kept setting up plays and giving Akali kills to help her recover, but
after hooking Ashe and letting her use Zhonya's, he should have just finished off Ashe, but he left the fight to go for Viktor; Ashe respawned, he couldn't catch Viktor, and they got wiped out.
Every fatal mistake that blew the games was Faker's.
Next was the jungle, who tried to help, but the bot lane was pushed around throughout Game 4.
Considering Doran was constantly being dove in top, he did his job in every skirmish except for Game 4.
