I am not sure what the best control scheme is because I am not really a fan of any of them.
I typically use Recon however with the new aim system it seems slightly more appropriate for it to be on a different button. I like where it is on default but melee is a bit poor on its location.
What I would like is:
Melee to be B
And
Aim to be Left Trigger
Other than that I am enjoying the game quite nicely
At some point you will be able to remap the buttons on your controller and do this

At some point…
lol I can do it now with the preview dashboard.
But I stuck to the default. I tried other ones but they were horrible lol.
Soon the app will come out that will let you remap your controller totally. I am liking default a lot. The beta had me spoiled with a nice feeling layout, when I tried to play mcc it sucked for a while.
I use bumper jumper but that’s just because I’m not used to anything else. I like to keep both thumbs on thumb sticks whilst jumping but I think it all comes down to personal preference.
Im using recon. Its wierd with the new abilities but its pretty easy to get used to
I can already do it, you need the app Xbox accessories.
Although I have the elite controller so it might not have rolled out to standard controllers yet
Yeah aim with left trigger and b for punch would be nice, not sure how that’s not an option at launch…
I tried to get used to default control scheme last night, but kept scoping when I tried to throw grenades. I think I’ll opt for the Halo 4 or Recon scheme.
I’ve used Bumper Jumper for years, but I’m really liking Helljumper right now.
It moves the Smart Link to L2, Grenade to R1, and Melee to Right-Stick. Pretty natural for me seeing how I’ve been using Jumper since Destiny.
If it could be perfect though I’d map it this way:
Crouch - B
Sprint - Left-Stick
Reload - X
Bumper Jumper
