1. They'll never allow more than three or else the game would get saturated with the hard to get stuff (more than three nightfalls a week, endless strange coins, countless raid drops, you get me). 2. Why? 3. Yes. Definitely. More vault space for sure. Or just don't separate it. I have 3 things in armor, but a full weapon cache. 4. I'm torn on this. It would be kinda cool to get like, tokens then have a raid vendor. But a buddy of mine got all his raid gear in one run on his alt character. That would be impossible if they went the route of getting currency from the raid (unless you have another alternative altogether?).
