Oh, but you are wrong my friend.
If you would have played Halo (in the last 2-3 games) you would be familiar with "MLG, Grifball, Race" and all other kinds of community made playlists that more or less use only community-made maps, and are far more popular then Bungies own creations.
Furthermore on regular basis Bungie implements some maps into matchmaking, accepting that those maps holds at least the same quality as their won, if not better. Not to talk about the thousands of customs games played on custom maps.
Go to forgehub and be amazed by the number and quality of maps, despite the "limited" tools
Great maps can easily be done on consoles, and so can a good map editor. If it is hard to make maps, less newbies will try and hence you automatically get less bad maps, as only experienced and good people would invest the time into making maps...
It can be hard to believe if you are "stuck" at PC, as was I one in the time, but the new consoles (and the next gen) is a lot more then mere consoles, and the gamers are more hardcoe, and less casuals.
The whole map editor for Halo was released due to modding and creating of custom maps back in the days. Bungie supported it and now it is a must-have feature for the games. Just like in the good old days of Unreal or CS
