And yes, as others have mentioned, it would also have made sense to have a bunch of additional ranks between Rock Legend and Completionist. It wouldn't have to be something as complicated as an RPG skills tree, where you get recognized for your best instruments or instrument-specific skills, OR for you / your bandmates all-around high-level ability ... but that could be fun too! I'm sure they have figured all of this out by now, and that any future releases [RB4? Another update to RB3? No need to remind us how unlikely these are, especially the latter, we are all well aware] will seriously consider incorporating them.
