Multiplayer issues

Ok first I’m going to ask a general questions why did 343 mess with the health regeneration?
second question is why the spawning in this game is broken?
Complaints:
343 haven’t you thought about learning things from bungie at least a thing or two. Why change and mess with the game when you didnt have to. All you had to do is release a new halo thats it we all love how halo 2, halo3, and halo reach multiplayer gameplay were. Now i understand that you guys are a different company and trying to make something new to the community. And honestly i love the new game mode warzone. And the game is great. But what really needs to be fixed is the spawing and the health regeneration. And i did notice that in war zone there are abilities that help with health regeneration. But still just return it like how it was in the old halos. Please im asking out of courtesy of the game and the community that you fix these two issues
Thank you.
