Questie is showing quests as being green colored instead of gray for a wider level difference than Blizzard is doing.

For example: char is 33, quest is level 27 and i already don't see it anymore unless i track low level quests in Blizzard tracking menu. Questie still thinks this quest is available, but green difficulty. According to Questie, this should turn gray when I'm 8 levels above, so at level 35.

"Trivial level scaling changes with each expansion
I think we're using tbc math and it's possible it changed in wotlk"

It seems in quest log it's green, but just not showing the yellow quest mark on the NPC. Blizzard consistency <3
