I think Campaign and Multiplayer should be treated differently. Why? Because I LOVE having multiple weapons, it's fun, and keeps the variety. However, I'm now very aware of what negative effects it can have on Halo multiplayer.

So, in regards to treating them differently, I'd like to see multiplayer have limited choices of weapons. As in, there's 4-5 different rifles in Campaign mode, but in Multiplayer, you're only going to see 1-2. If you want to see more, then maybe making the other weapons some kind of option in Forge/Customs.

I mean, remember how useless the Sentinel Beam was in competitive play in Halo 2? (Or maybe it was useful to 1 of you). That doesn't need to be in an actual arena map, but it's really fun to have in customs!
