I feel like this would only make us use other curios then the ones that are best right now. making it so some other curios become the least used ones.
so all in all it seams pointless, as we would go from studying x curio now into studying y curio later (making x obsolete instead of y)...
the same effect could be made with a simple rebalance of numbers, if we now for some reason want ppl to stuy other curios.
