I recently finished my Shatar Skyguard reputation grind. I'd previously done my share of rep grinding, including repeatedly decimating the populations of Felwood Timbermaw and Nagrand ogres, but I was, um, not prepared for Skettis.
We tend to be a friendly group on my server, and my previous experience rep grinding involved everyone giving each other a respectful distance, taking turns and sharing a friendly wave here or there. It is quite a bit different in the cutthroat world of the Skethyl Mountains, where more than once I detected stealthed Alliance lying in wait trying to grab my summoned mobs. When it came to summoning Terokk, I quickly learned to save that for early mornings and to scope the area beforehand just to be safe from Allies, but quite regularly, someone of either faction would swoop down into a camp where I was merrily grinding away and kill the very next mob in my sights, regardless of the fact that the next camp over was completely unoccupied. I had no idea Skyguard Rep was such serious business!
I eventually finished my grind and earned my Purple Riding Nether Ray and matching Nether Ray Fry, but I am still surprised by the experience. Ever enter into a WoW endeavor to find it unexpectedly competitive? Did you stick with it, or did you decide it was more trouble than it was worth?
