Custom games a disappointment in halo 4?

From what iv read on waypoint and from what iv played it has been a disappointment. Custom games is what makes halo amazing! makes forge look like an amazing part of a game that no one else has. All i used to play in halo 3 was custom games. it was the most fun, because it was our game types and maps that we made, not bungie(halo 3) or now 343. We need a lot more options and freedom. NEEDS TO CHANGE.
