Man, Commander Niall was a grind! The amount of times I ran up to his cloud gate on my first playthrough was sickening.I keep getting "lost" as I disappear off having found/seen something, and deviate from the very loose story. Ranni seems to be the only one that I've followed...ish
Only now have I got to Consecrated Snowfields, having defeated Commander Niall in 2022, and again recently - not NG+ but some wierd save bug I guess.
Holding off DLC, until my inner magpie is content enough shiny things have been discovered in ER! Will be soon though.
I made sure to get Tiche to level 10 as a spirit summon on my second run through as I just wanted to get DLC ready and she absolutely melted him (and most other bosses)
