This weeks buff is Classic Quest and Reputation gains ETC. I don’t see a Chromie Time for Classic, so how are you suppose to get EXP for Quest from Classic if there is no classic Chromie time?
There isn’t a Chromie time for Classic because the world was revamped in Cataclysm expansion. However, it should affect any quests that reward rep for a faction under the Classic header in the Reputation pane, at least for ones that still have quests available (e.g. racial factions, Steamwheedle Cartel, pvp factions)
