I seem to remember them changing how much 7th Legion and Honorbound reputation you gain from simply doing the quest chain to make it easier to progress the War Campaign story. I think I may have done some of the campaign prior to the change so I had to make up the difference.
It wasn't that much work, but it was still something I had to spend time working on because I couldn't just accept and do the quests, because I didn't meet the reputation requirements by default.
Either way, the main point is I feel like the main story line of the expansion shouldn't be tied to a reputation level.
