There seems to be an issue with Chromie time after the last server reset.
When my characters level up, i.e from 20-21, the mobs all stay lvl 20, giving reduced kill XP. This has happened with 3 different characters I leveled up today with different levels. All the NPCs that are supposed to follow your level stays put. I haven’t compared, but this may affect quests and quest XP as well.
Zoning does not fix the problem, neither does logging out, even for an extended period of time. I also tried disabling Chromie time, and the Azeroth mobs on my lvl 44 character correctly capped out at lvl 30, but when I turned Chromie time back on, the mobs got back to lvl 43, so the problem persists through that as well.
I haven’t tried leveling up another time to see what happens because my leveling method becomes quite ineffective with mobs one level lower.
