fair enough

: probably not shared by many.

There aren't any broad similarities between the beta and Destiny that I can see that they don't also have in common with "Halo Classic", as it were. They're both more fast-paced than most Halo games, but Halo 1 and Halo 4 (boy is that an odd pair) make it harder to call that a real change. Where they get more similar is in sharing specific things that older Halos don't have, specifically:
- the ground pound
- a stronger melee while sprinting*
- the ability to zoom in with any weapon and have it affect aim
- allowing players to sprint as long as they want†
- the thing where zooming in while jumping/falling makes you hover
- the ability to slide by crouching while sprinting
- giving most weapons a headshot bonus‡
- replacing crouch jumping with an ability activated by the jump button

It's not a matter of opinion that all of these things are in both Destiny and the Halo 5 beta. I'm not saying they were taken from Destiny, they were almost definitely taken from other games that Destiny and Halo 5 both drew inspiration from.
I'm honestly surprised myself, I thought there weren't that many similarities until I listed them all out.
Where opinion comes in is in whether you like these things. Personally, I like some of them and dislike others, and still others I'm not sure about. I would like almost all of these changes better if they weren't there all the time.

* I think some Halo games had a walking melee do a bit more damage, but nothing like this
† this was possible in Reach and Halo 4 but only in multiplayer and only by using a custom powerup, a perk (armor mod?), a trait zone, or a custom gametype
‡ or so I hear, I haven't seen it an action in the beta
