Grenades are changed using the d-pad, and ordnance is selected using the d-pad. A number of times I have been in the heat of battle, saving my ordnance for later, tried to switch to a different grenade and wasted my ordnance.
These two functions are the same for all controller layouts.
Has anyone else encountered this problem? Does anyone have a suggestion on how to fix it? Is it too late to be fixed?
I noticed this too and it has happened to me a couple of times. Hope there is a way around it but thinking there’s not 
I have no problem with it, perhaps because I don’t switch grenades often.
Does UP on the D-Pad do anything (besides activate editing mode in Forge)? Numerous times I’ve accidentally called in an Ordinance Drop while trying to cycle to my Plasma Grenades. Grenade swapping should be re-mapped to UP on the D-Pad. Obviously this won’t work for Forge mode.
I play Bumper Jumper, and “A” used to cycle the grenades. Nowadays “A” makes me sprint. Can we get a controller layout that has “X” sprint and “A” cycle grenades? This controller layout could have “Guide + Y + Up + A” activate the AA ability.

Moreso than that, why is it so difficult to just let players map buttons themselves? I don’t understand why we’re locked into this handful of static controller button layouts. I used to be really good at jumping to high spots in older Halo games by clicking the left thumbstick down while jumping - but now it’s B by default. It’s taking a lot of time to get used to this,and I’ve been missing a lot of jumps as a result. I have to practice more with the other layouts to try and get over this issue… but then I have to acclimate myself to other buttons being in weird (to me) spots as a result. There are elements of a few of the layouts that I like, but not one with them all together. It’d just be so much simpler if I could just map the buttons the way I wanted.
