I would say don't use Manaward on that part. Your healers should be shielding you. This allows you to save Manaward for the very beginning of the last phase. As soon as you come down from the ATB, you can use Manaward during GA-100. This way you can stand dead center, surive GA-100 and then you don't have to move to position for the first Optical Sight.
