The sides should really really really really be made more narrow. When you look at other maps, none are as open as that. Making it open gives such less control and makes it SO much more difficult to play on. It's also useless. As one rarely ever uses anything other than the main path, it's better to just cut the map back to what actually matters here and then work on making the main route BETTER.

You're really not losing much of anything by cutting back the sides. The open area is just a waste. When you look at essentially every other Halo map similar in design (icefields, danger canyon, wartorn), they all have more narrow vehicle paths than this.

This all goes back to what I said before. You can have a lot of detail in a smaller space, or a lot of space and no detail. The smaller space and more detail is what people want to see, and it's what makes one map stand out from another.
