Bungie's previous games have had crouch mapped to L stick click since I can remember. Now, you can only map it to a stick click in the "puppeteer" control scheme, and that's only on the R stick click. This is an issue for me since I've been clicking the L stick to crouch every time I stop moving in most FPS games for over a decade. I can't imagine I'm the only person who is trying to work around this. For me, personally, I greatly prefer Jump, Grenade, Sprint, and Jump functions all mapped differently, as well. This game is crying out for fully mappable controls. I hope Bungie at least sees this and gives an option that ONLY switches the stick clicks. Whether this issue gets resolved or not, I'll still be playing. If the beta is any indication, the game will be great, and it's amazingly easy to play with friends. Seamless.
