My Champion hit level 75 in LOTRO, which brings me back to the level cap, albeit for a relatively brief time.  I finished the main story from the Isengard launch, but plenty of content remains, including the entire Great River zone and large portions of the sidequests of Isengard. 

Not much new to report here, but one minor quirk - because Turbine's model offers free players access to the current level cap, exterior zones, and epic story, it is important that I finish this content now, rather than after the expansion.  There's no option not to purchase the new level cap, and therefore no option NOT to advance beyond it until I've run out of content.  Ah well, at least it's been a good ride thus far.
