I don't really mean "exploit". Maybe that's a bad word to use in this context. I just meant people could endlessly trade marks for mats, then mats for crucible marks and so on. I wouldn't mind it, but I can see how it would bother the almighty bungie brigade.

That's what I mean, there shouldn't be a problem with it but seeing as how they patch some other stuff I am guessing they are using it as a way to try and get players into pvp? That is my only thought about it or maybe they didn't realize that they did it? i don't see what the difference would be from grinding for mats and trading them in for crucible marks and buying mats and trading them for crucible marks at a crappy return rate.
