The shotgun should be set on the map and not in a Loadout.
The Magnum and the Focus Rifle are perfect. Do not change them ! Many people say the Plasma-Launcher is too powerful. I don't think so. It is difficult to aim with it, and it doesn't have a lot of ammo. I just hope we'll see the fuel rod gun in the final game. The Energy Sword has to be improved.There are many bugs with it. Sometimes the guy dies, sometimes he's only hurt. When he meeles you, your hit doesn't kill, and he meeles again, and you die. I want Halo 3's sword back ! But the idea Sprint/Sword is good. The camouflage isn't very useful, because when the motion tracker is jammed, the enemies are careful and see you quickly. It would be a good thing that this ability doesn't jam the tracker.
A suggestion : when you shoot with the Grenade Launcher, and you hold the trigger, the grenade goes away and you don't see it any more. On the GL's screen, there could be a light (red, for example)which would warn you when a guy is next to your grenade.
Frag grenades should only break your entire shield, and not hurt your life. Furthermore, the radius is too big.
The Rocket-Launcher is very powerful. Okay, but you die, or you're not hurt. The damages should decrease when the opponent is far from the explosion.
The different colors on the motion tracker is a good idea, but it is difficult to make the difference between the guys next to you and the guys above you.
It is also difficult to see what kind of grenade you have.
Sometimes I want to stick an enemy, and.... I throw a frag grenade.........
