As a Vanguard you will have to repeat ANY (1) of the Vanguard Challenges once a month (30 days) and maintain the highest MR rank -1.
This is to ensure Vanguards are up-to-date with current meta/content/proficiency.
Any New Content DE releases (that is end-game viable), will be added to the Vanguard requirement list above -- it will be introduced and will count toward the monthly challenge.
- Failure to complete a monthly challenge will result in demotion back to Guardian rank
- To regain Vanguard rank, simply complete (any and all) monthly challenge(s) missed.
