Thinking about what her next rep grind can/should be, I took a look at her reputations on the Armory... and there, sitting at the top of her rep list, is Wintersaber Trainers.
Hey, isn't Winterspring going to get revamped in Cataclysm? Uh-oh... By all reports, it looks like this will take about 25-30 hours of grinding to accomplish. Might as well just get 'er done, then.
In the meantime, I realized that there are a couple of daily quests in Outland that I could be doing to work on my Ogri'la rep. I was under the impression that the only quest you could do to raise Ogri'la rep was the incredibly annoying Relic Emanation quest. I completely missed out on the fact that Wrangle More Aether Rays! and Bomb Them Again! give Ogri'la reputation as well. So it looks like about a month or so of running errands for the ogres, and I should be able to get another faction to exalted, plus an achievement - since A Quest a Day Keeps the Ogres at Bay.
