Well in "Disaster" it was almost as if O'Brien was in command, as Troi generally decided to follow his advice rather than Ro's. But as Ro's was basically seperate the ship and leave the people in the stardrive to die, I can see why that idea didn't sit well.
O'brien was playing the part of wearing Troi's pants(ha!
) very well in that episode.
Ro's idea, while it may not "sit over" well, was likely the most practical idea to save at least half of the crew instead of losing everyone.
Ro was an extra though, so she had no idea that the main cast invariably pulls victory out of their butts at the end without fail.
