definitely I would change!

row 6 and 7 are separated from other C-class seats, 2 galleys, 2 toilets and directly connected to eco; during the flight from NRT you always have people from rows 10 to 15, who do not want to go back to "their" toilets in eco (behind row 25), always noisy and crowded. In addition, row 6 and 7 the selected meal might be gone, as you are the last one to be asked about your selection. They do not always go by m+m hierarchy!
