When I think forge, I think of a game mode with creation options, a test to see how mind blowing a community creation is. In the past forge was just a game mode to make a simple map at an extremely limited option base, Halo 5 increased the options massively of coarse at some cost. The cost was difficult to get used to as it was the advanced controls.
My list will contain wishes I have stumbled a crossed on YouTube videos and my own wishes.
1: Classic controls, or at least as close to the classic controls as possible to fit with what we could have.
2: An advanced editor, by this I mean creating mini missions where rounds of AI are dropped in an area to accomplish a goal, kinda like a firefight. Just think, place down a spawn point for drop ships to fly to and drop off enemy AI.
3: Forgable AI, I know i should have made this number 2 but hey, at least its on this list!
4: Vehicle properties, and I don’t mean like phased cause that was brought in halo 5, I mean Drivable, Undrivable, Destroyed, Damaged, ect.
5: XXL maps, I say XX because I count the halo 5 maps XL and Halo Reach’s Forge Island L.
6: Large drivable vehicles, I have always wanted to play around with the pelican in forge especially when halo 4 allowed you to drive one for one mission. (Reason for #5)
7: Classic/Mission items, It would be cool to see the items in halo 4 forge and the other halo games with forge make a return and items only seen in campaign would make forging campaign themed things a lot easier.
8: More forge options. Better colorization, more skybox, and some new options like landscape editor.
9: Vehicle returns, It would be cool to see the well loved falcon make a return to halo, revenant to.
And finally,
10: More Military and Urban themes items,i could have easily said more items but I like but I like these item the best. Covenant stuff to.
