Possibly a stupid question, and something I've never really paid much attention to until now... At what point or rank does character become eligible to earn vanguard marks? I ask because I've finally gotten around to levelling up my Warlock this morning and happened to be in the right places at the right times to encounter 4 public events. With help from other random players I got gold tier results in all of them and was awarded ascendant materials for at least two of them, but didn't get an vanguard marks. Any answers would be greatly appreciated.
