I am sure you all have but I found this vid made by Arbiter617 that highlights the things most forgers are so mad about in the new halo 4 sandbox. Some of the stuff doesn't apply anymore because it has been fixed so its a little late for that. But I still found it humerous. Halo 4 Forge | Parody ViDoc - YouTube
Pretty sure it had its own thread or at least a good two-three page conversation in the halo 4 discussion thread.
