Know what I really miss?

Hidden League Gaming, or hiding spots in general. That was one of the many fun things about Halo 3. There were many hiding spots although most, if not all, were unintentional on Bungie’s part and the majority were later on patched save a few such as the rooms above Red and Blue spawns on The Pit. The trend continued with Halo Reach although to a lesser extent and such spots were largely abused in gametypes like Infection, especially that one crawlspace in the center of The Cage. But now it’s 343i’s turn, and I can’t help but wonder how many hiding areas there are waiting to be discovered in Halo 4 that the testers are yet to find and patch.

No

I had so much fun in Halo 3 with HLG. Good times. Hopefully Halo 4 will be aa bit better for hiding than Reach was though.
