For the Gen 5 challenge "Critically Conditioned: Charge Rifle", I need to get 30 critical hits with the Charge Rifle. As any good Titan isn't standing in one place very long (and even if they are they are rotating and slightly gyrating), lining up hits is tedious at best.
I had the thought to rodeo and use the Charge Rifle, but while it seems to give a 'red' hit indication around my reticle, my challenge progress is not ticking up any. I've heard rodeoing is a way to do the challenge, but I'm not sure what I could be doing wrong. Does the Titan's shields need to be down before a rodeo shot counts as a crit? Is it bugged? Was it patched?
