The first and foremost that a quest tracker does not exist in the classic version like the retail version of WotLK did have, which was weird cause quite a few quests in northrend are very vague and some don’t even say their location, mostly they’re just doing story telling for them (which I liked back then) and it’s annoying that we have to use an addon for a system that was already placed in.
The other beef I have is shamans not being able to use ghost wolf in instances, like the quest tracker this was also in retail version where classic does not. Everything else so far I do enjoy though.
