We need Grenade change on "A"

Please 343, do NOT change the controller! Bumper Jumper needs the grenade change on A!! Like it is now, it’s awful

additionaly, for all who are used to crouch jump, this new ability when holding the left stick is -Yoinking!- annoying!!! I am used to pushthe left trigger and here I always get stuck in midair when I do this. That sucks!!
