One question: You’ve got Badge of Motivation listed, but Badge of Stealth pictured; which did you mean? Or maybe both? I haven’t needed to farm for Badge of Motivation since around mid-Red ranks (which is right where you’ve reached), but I still need Badge of Stealth badges occasionally.
Anyway, the good news is that a few of these badges may drop off your list before much longer; the mid-Red ranks is also the last time I had to farm for Sugar Rush and Embrittlement Perfume badges, and at some point my main account no longer had to farm Imagination Ship bits, although my backup account still does. The bad news, of course, is that a lot more badges will be joining that list: Lucky Cricket, Magical Breakfast, Driving With Style, the list goes on and on and on.
PerBlue could alleviate the situation somewhat by putting the scarce purple and orange (and now red) bits in more new nodes: Potential Carriage, Close Shave, and Dinglehopper bits, for example, are available on only two nodes apiece; meanwhile, PerBlue keeps adding nodes for overabundant badges like Nope! and Love Birds. But it does seem that PerBlue believes manufactured scarcity is the key to generating more sales, so I wouldn’t expect that to happen.
