Today I read somewhere that Bungie is not happy where you team can not have defined roles when running the Vault of Glass. I hope that this is not the case because I would have to ask them why did they make three different character types whose skill trees provide different team support? I understand you want everyone to experience the same thing, but it should not be up to the game to decide. That is why you have fire team leaders. If there are people complaining about being stuck in a role in the vault of glass, they should complain to their fire team leader. If that fire team leader doesn't allow that person to hold the relic, then find a new fire team! There is not a single MMO out there where a player is not categorized by the role they best fit. That is because in order to be successful in a raid, everyone needs to know what tasks they are responsible for. If you don't like your own raid because people who know how to coordinate and play their role can beat it in less than a half hour, then the lesson learned is that you should make the raid longer. Not just two bosses and three "mini-bosses".
