In a wonderful world, the default maps that would have come right out of the disk would have been:
1. Powerhouse
2. Anchor 9
3. Battle Canyon
4. Tempest
5. Breakpoint
6. Spire
7. Boneyard
8. Solitary
Why, you ask? Because all this maps have Rockets and Snipers.
Why Bungie decided to put so many Shotguns and Swords in Countdown, Zealot, Sword Base and Reflection is beyond me.
Half of the reason why Reach failed was because of horrible maps that came with the disk and dumb weapon positioning, that promoted crouching down and camping with a Shotgun or other close quarters weapon.
I don't know why Bungie didn't even thought about putting a single Spartan Laser in ANY map. In fact, I don't know why they even added the weapon if it was only available in customs, Breakpoint and Highlands. (lolParadiso)
The Focus Rifle was only available in Powerhouse and Breakpoint. The Concussion Rifle was only on Countdown and Zealot, but nobody goes for the Zealot one anyways, and those who pick it up on Countdown can't do much with it.
The blue berry gun aka Plasma Laucher appeared far more often than the iconical Spartan Laser, yet it sucked for anything else than taking out tanks.
TL;DR I hope Halo 4 has more Rockets and Snipers and less Shotguns and Swords.
