With "right stick" being look, and "A" button being jump, I found it utterly impossible to perform some of the jumps I've been seeing on YouTube. After some experiementing and practice, the best solution I've found is to remap the "jump" to "Left Bumper." This allows you to sprint, look, jump, slide, and shoot! simultaneously while never having to take your thumbs off the steering sticks.
In the end, as a Light Op, this has made me love being a Light Op sooo much more, performing these crazy wall hops and jumps...juking about and escaping fire, flanking, etc etc. And it most definitely brings out the best in the Light Body Type, and has opened up new routes and made traversing the maps much much faster...and more fun!
Hope this helps!
As a side note: I set my controller config to "Duty Calls" and then remapped my "Left Bumper" to jump.
