First impressions matter.
Sorry, this is a little long-winded, but 
Now I get that this is a beta and adjustment will need to take place, but IMO this doesn’t feel like Halo outside of the artwork that has always been appreciated, the time and effort the teams takes to put in creating the skybox, the designs for the gear/weapons, etc… in that aspect, I have to say thank you to 343 
It has always been something I have enjoyed that is part of the reason I have bought every single Halo from Bungie/343, giving me the incentive to explore. But, and there is always a but.
Halo will always have its fans some new and some that have been around a long time to know how things have changed way too much from Halo 4 to this bata, each game feels different and that is a problem because of the lack of (consistency) a company not learning to stick with what works in a game and improving things from there.
The #1 issue some companies haven’t learned is when you constantly change things you are leaving a hell of a lot of room for problems/issues/complaints, etc… and a lot of unhappy fans that doesn’t benefit the company nor the player base having to spend that time and resources changing what they changed that didn’t need to change in the first place. Take the original Halo series (consistency matters…)
This might not be the best example, but this is what happens when things change too much. The game The last of Us, part 2. IMO the game’s potential was literally destroyed. I know opinions will vary and there is nothing wrong with that. I’m just tired of seeing games that have the potential to actually become a great game being ruined over flawed logic…
