Yeah, I really think a lot of changes need to be done before this gets released. 90% of the weapons are useless if you go against a team who just wants to camp or hide with the power weapons.
The hammer, sword, or shotgun with speed burst or invis are nearly unstoppable.
The shotguns range is a lot bigger than Halo 3, but I don't think that hurts the game. Just when people are camping with them, it's pretty retarded.
The lunge on both the sword and hammer is ridiculous, especially with sprint. There isn't much you can do to stop these. There are just too many corners and places to hide. Giving people the ability to be invisible every round pretty much sucks.

The DMR is a terrible replacement for the BR. It's pretty much a sniper rifle, without the power. It's near impossible to 4 or 5 shot people with it for a couple reasons.
For one, it doesn't shoot quick enough, and if you shoot too fast, the recoil messes up your shot. You have to have 4 or 5 sniper type shots since there is no spray.
Second, people just run or roll out of the way.

I am not sure what they can do to make it more balanced. As Drew said, it's mostly just AR's spraying wildly with beat downs, grenade spamming, or the power weapons and camping. It really takes away any skillful gaming, and makes you just want to hide.

I guess since it's only the beta, we can't complain too much. But, IMO, it needs quite a bit of work.

EDIT - Wow, we were both writing up our complaints at the same time. :rofl:
