So it is come to my attention that there are two achievements that require you to get a certain amount of score within a week. These two achievements are Called: Notorious and Valorous, I'm just a bit concerned about this because my lil cousin has just started his XBL account ( prior ) to a month ago. He eventually started playing Destiny. Around the same time which makes him a year two Guardian. This post is also entitled for other year two Guardians whom are a tad new to the world of destiny. Are these achievements still obtainable for newcomers for year two since there's no score count or mark tracker for vanguard or crucible marks being earned within a week? How? And is obtaining these achievements still even possible?
