You're missing what Halo is at its core. Halo has ALWAYS been about:
1. Timing power weapons, and it's better if they're on static timers
2. Timing powerups, again, better if on static timers
3. Controlling the map
There hasn't been a proper utility weapon since Halo CE and I see that they have a much better weapon balance in Halo 5, but you're missing my point when I say Halo 5 is missing the very heart of what Halo is.
343 can keep Halo 5 the way it is gameplay-wise in regards to mechanics, etc.
What they could easily implement is:
1. Floating weapons on the map with brightskins, e.g., like Quake, so they're easy to identify on the battlefield
2. Static timed power weapons
3. Static timed powerups, and put at least two of them on each map (depending on the size of the map)
4. Place counter power weapons on each map, e.g., rockets/snipes, sword/shotty, etc.
There is simply not enough going on in Halo 5 right now. If 343 are saying they didn't include powerups and more power weapons intentionally...then fine, but show me what the final is actually going to look like.
If Empire in the Beta had a rocket and snipe that dropped on a static timer, as well as an OS and camo nearby each power weapon...then we could realistically see how Halo 5 truly is.
If this is suppose to be a beta to give feedback on the core of the game...having features and items absent from the beta negates the entire purpose to begin with.
Game is boring as hell right now. Nothing to control on the maps. It's just sprinting around slaying...with precision weapons...that's boring and it's not Halo. If all we wanna do it have a Halo game to test who's got better aim and better setups...well congrats, you've got that.
You don't understand Halo.
