Guys I'm Lost...

I see that a lot of people are angry about lots things such as:
The DMR’s new look
No Elites?
Random Weapon Spawning?
Two armour abilities at once?

And that’s all I know.

Can someone please provide links or tell me where to find this information? I’m on my iPhone right now and I’m having trouble finding any sources for these claims.

It would be much appreciated. Thanks.
