My idea on how the controller layout should be.
RT-Shoot
LT-Throw Grenades
RB-Sprint
LB-Armor Ability
Y-Switch Weapons
X-Reload/Pick new weapon
A-Jump
B-Melee
RS-Move/Crouch
LS-Look/Zoom
D-Pad Down/Up-Ordanance
D-Pad Left/Right-Switch Grenades
You need to swap your RS and LS but other than that, this should be one of the layouts. Call it “Classic” even though grenades would of been on LB but 343’s intelligent staff added sprint as a default setting.
