I think halo 5 should be about permenently destroying the flood like going to their planet i also think you should be able to play asd a marine at some point. Plus there are alot more rings to destroy.and we should also have to go to the forerunner planet and find some other guy and more oracles and the arbiter should take part in that
i also think halo 5 should be more like halo 3 and 2 those had the best campaigns in the halo series and if we can play elites we should be able to get arbiter armor even though it wouldnt fit in that well
