Yeah, another boring factor is Kira and Arthun just used Freedom and Justice MK-II at the end...
It would have been nice had Arthun kept his saviour gundam to the end...he and Kira used old mobile suit+superior skill+superior teamwork to match against Shinn and Rey??'s state of the art MS (forgot his name) should be a lot more interesting (but if that happens that Shinn would be downgraded to even more degree
)
