I think a rewriting & rebranding are due. I would focus on making the dice rolling system as stream lined as possible. RRs for example could be handled better. Trim the core skills down to 25-30 and explain in detail how to use them in a few different ways. One thing I would do (and do myself) is provide an "adapting rolemaster' sectioin that would give you options for using the same material in a more heroic scale of game.
