It would be nice if there was something that would keep me interested in getting brain upgrades. I feel pretty confident that TS will never release skills faster than I will learn them, even with a 2000% penalty. I'd like some repeatable skill that would give a small reward and maybe an achievement or two just to keep me paying attention to my brain. It would also give me something to do with the favor that I accumulate that I don't want to turn into emblems/icons.
