She is weak because her powers are weak.
If she was as strong as ichigo then her confidence would alright.
Although ichigo gets depressed everytime he gets pounded by someone stronger.
Having faith and knowing that her friends are not strong enough are 2 different things.
What false presences
Stay and her friends will die, go and her friends will live.
Since she cares about her friends and knows they will die if she stays, she has gone.
Orihime didn't just 'join', she saved her friends lives by 'joining'.
Since when does ichigo need to understand the reason for something in order to free his friends.
I find it so strange that people who dislike Orihime give these reasons.
Saying that she is so strong as her heart and she just need to strengthen her heart.
Like that will happen like that. Orihime may need to hit rock bottom in order to climb herself back up again and be a supporting character we would all like.
She may strengthen her heart but who is going to teach her how to use her powers.
Orihime has been alone for some time, her parents left her, her brother dies.
And now the person she loves is drifting away from her, atleast that's what she feels.
And when she wants to fight with her friends, she is told we don't need you, we have battle trained healers.
So go home and be alone again.
Even when she was told all that she did sit down and wanted to get stronger.
And don't compare Orihime with Sado, atleast he can fight, has the will to fight.
But then he and ichigo has been fighting all along.
Orihim has just been in fight just recently and couldn't do anything but healing.
