What your are saying is true, but here is the thing, 10 3 of coins is equal to 14 strange coins. I have (and assuming OP does) hundreds of SC's and can buy them from Xur every Friday. It is not worth my time to run the nightfall without the exp buff or faction rep boost if the rewards come out like this the majority of the time, so I don't bother anymore. (I do the weekly crucible bounties, but that is without trying, I just pick them up and they get completed as I play the game.)
