Well first off I'd like to say I get why they have two differentkinds of marks. They reflect two different play styles In which players can earn their marks in the way they want. Which would totally make sense if Crucible didn't run all of it. Now, I play crucible so this doesnt hurt me but the people who love pve and vanguard and screwed. If you want faction armor or weapons, good luck! You're not getting them with this shiny vanguard marks! I could go on about the different examples but why not put a universal mark in? Something you get from crucible and player versus environment and everything but then make the items cost more. It would make more sense and honestly most players don't even spend their Vanguard. Most people I know have a maxed out Vanguard and repeatedly spend crucible marks. Also besides putting a universal mark system and why not add a raid marks? To obtain items that your bad luck has stopped you from getting in the raid! It should be extremely hard to get and obtain large amounts of but it would be fair. Also besides that are universal mark system what make and vendors and all of that stuff a lot more interesting and universal which would make the game run a lot more smooth and people could still have the choice of doing whatever they like.
