I used a Sons of Hodir token from the daily dungeon quest in WotLK classic and it set my reputation to Hated. Can I get my rep restored to what it should have been?
Sons of Hodir is an interesting one where we all start at 0/36000 Hated with them until we do the quest chain to unlock them, then that rewards a huge rep boost to bring us up to Neutral. So if you use a token before you unlock, it applies it to the (previously hidden) deep Hated level and makes it look like you suddenly went backwards.
I am not sure if unlocking them now will bring you up to (Neutral plus one token’s worth) or just to Neutral, wasting the token. But I would still unlock them before using any more.
