I'm at around Rank 4 at Nightfall, but I'm trying to get the last "Season 4 Exclusive" Triumph and Season 5 is coming now at 27th Nov. I thought I had time until 4th Dec. When Black Armory came out so I'm running out of time. My question to you is: Can I go up in NF Rank by doing the same 3 NFs in 100k? or can I just get XP by doing 100k on each once?
