said by Alpha Phoenix:Yah. I really wanted to see Toph step in and kick her ass.
Yeah, that would have been awesome.
Have Toph come in when she did and definitively defeat Kuvira. Then while in prison she escapes or her people (a spy maybe) free her. Korra asks Toph to confront her again but Toph takes the same attitude she had about the poison in Korra's body because her family (Lin Beifong and the rest of the Beifong clan) are out of danger. Toph also does nothing because she knows Korra can and should defeat Kovira herself.
So when Kovira attacks Republic City Korra is forced to woman up.
Any Avatar, not just Korra, should have been able to destroy Kovira's weapon with little trouble as well as Kovira herself. The Avatar state is a collective of wisdom, strength and power from past lives combined with Raava. Therefore issues specific to Korra while in the Avatar state should be like a single raindrop in an ocean or to put it another way "inconsequential". She can workout her personal $#!t when the fight is over.
It seems like the writers wanted to make Korra a victim even in the first season when Amon took her bending.
BTW, I didn't even know that Zelda Williams (daughter of Robin Williams) was the voice of Kuvira. Wow, she has a great voice. The show has had an amazing cast throughout the seasons.
