Zadnor scaling is definitely not working properly, especially in zone 3. Sometimes you can have 20 people in the zone doing Fates there, a new one pops and it melts in 20 seconds like it was scaled to a solo player. Meanwhile some zone 1 fates feel scaled to 20 people even when no one is in the zone.

I could understand the mechanic behind it to some extent in the Southern Front. If a Fate spawns in zone 3 while everyone is in zone 2, it gets scaled down. But Zadnos fates don't seem to follow any logic or mechanic. Some of them just melt regardless of players in the area and some take ages to chew through.
