I'd like to see the return of 2 characters. The Arbiter and the Didact. If you think about it the Arbiter is still on Earth because his half of the Forward Unto Dawn got through the Slip space portal in Halo 3. The Didact should return because he is far too important to just kill off like it seems apparent in Halo 4. But I think that he the orange spiral he fell into was a Slip space portal and he is just lost in space somewhere. He is pretty much the most important Antagonist of the entire Halo story and I think it would be a great shame if 343 was to discard the Didact. Halo 4 is the first in the Reclaimer trilogy and I would really like to see the Didact and the Arbiter in at least Halo 5 if not the probable epic end to the story in Halo 6. The Hornet from Halo 3 would be nice to see again and I think more customization in the armour in multiplayer would be nice, like the option to change the colour of separate limbs etc. Also I prefer the Xp that was used in Halo Reach to the new SP (Spartan Points) in Halo 4, maybe going back to that could happen. But apart from those things, 343 you're doing a great job! Thanks.
