I thought it was interesting that Thor's presence for the pro-reg team seemed to tip the balance so heavily in their favour. Even though its not really Thor.
The only hero who seemed unphased by his presence - and who seemed to have the power to block his power - was Sue Storm.
Now she's left the pro-reg team to join Captain America's squad (taking Johnny with her) I wonder how this affects the balance of power. Not just because of her powers, but also because of her very influential place in the world.
She is incredibly powerful in her own right - but I wonder if Sue's decision to back Captain America will be shown as being monumental or just as one more hero swapping sides.
