Yeah.. Im not a fan of lower level sacrificing rewarding you with MORE common souls. You actually HAVE to sell them to get rid of them because throwing 10 1 or 2 stars in the grinder is still going to get you back 3 to 6 souls. I guess some may like that. I find it jsut tedious.

There should be way to jsut sell souls without dropping them in the BOS.. or like you posted. convert 99 common souls to 1 rare.. or whatever. With frags now.. 99 common for 25 rare frags (half a rare soul) would even be better.
