Vanguard: Saga of Heroes E3 Preview

MMORPG.com has conjured up another E3 preview, this time providing some new details about Sigil Games' Vanguard: Saga of Heroes. An excerpt to follow:
Another controversial feature of Vanguard is that, in some quests, especially those for larger groups, players may run into a part of the quest that requires a specific profession to proceed. For example, a goblin diplomat may only be willing to speak to a diplomat of the proper faction, or you might need a certain type of crafter to clear away a landslide. If you don't have what you need, you either need to find someone who does or abandon the quest. As McQuaid and Butler see it, players are not entitled to access all content. If you are a soloer and 20% of the game is solo content, with 40% for groups and 20% for raids you need to accept that you cannot access group content, or join a group.
