I want to hear what you all think of the new beta! I've been playing it non-stop over the past few weeks. I absolutely love it, and this is coming from a player that absolutely despised 343i's Halo 4.
The new abilities don't ruin the gameplay. Ground pounds are surprisingly difficult to get, so they are far from overpowered. The dash ability is a nice tactical touch. It can get you out of some sticky situations if you're fast with it. Also, I think the assault rifle might be a bit overpowered, but it's nothing too serious.
The fact that everybody starts with the same loadout is just plain beautiful. It's what made Halo such a great game. Balanced teams, balanced maps, and power weapons to fight for. It's great to be back.
