Add Forerunner and/or Covenant building blocks to Forge.
There have always been complaints about how Forge maps look bland due to them always looking the same (Olive-Drab boxes in Halo 3 or a dull-grey metal in Reach making up the entire map).
Why not let people be able to choose between themes, or even mix together themes?
Reach’s forge pieces had a forerunner theme, but people said it was too grey. I actually liked it better that way more than the bland off white unsc pieces we have now.
I would also like to have an option that allows you to pick the style of the pieces. Show what base is for the covies and what base is for the humans.
I think it needs to go further than this. We need pieces that are effectively colour bars to better design the structures. Many structures are clearly an assortment of different pieces, we need things to help link them together aesthetically. It would also help us move away from the one colour perception.
