@7th, thanks. I was just curious. Sadly in an attempt to stagger my Reach playing I ended up breaking the whammy bar on my RB2 guitar whilst playing some new tracks. sad days...Same one most ordered from Neweggs that came bundled with AC/DC. Oh well, it still works just no spring back action. I'm going to wager a guess that cR earned after you reach the cap are just spending cash while the actual "XP" earned is frozen as if you have reached the highest level attainable online. In theory, this would prevent players who have earned enough cR by the time the cap is lifted to be power leveled into General and beyond etc.
Yeah, only ways to get down is the yellow lift, of course landing on someone's head, jet pack staggering, or being air lifted off. At least these are the only method's i've seen online, have tried, and can think of. Besides, it's cool up at the spire.
