Nikol of WoW Ladies posts about something I shouldn't get so worked up about, but often do anyway-- higher level characters farming mobs that lower levels need for quests or rep.
Now, Nikol is actually on the opposite side of the equation from the one I remember being on more. She was wondering if there is a certain etiquette when she goes to farm Timbermaw rep (as a level 68) and starts competing for mobs with level 58s. Which is actually very nice of her, because usually I'm in the other situation: I'm playing a lowbie alt and I have to go kill 50 pigs to get their spleens. Suddenly, a level 70 mage roars through the area, AoEing every pig he sees, rounding them all up in a pile so he can level up his skinning. A few seconds later, I'm left with nothing to farm, and he's standing over a pile of piggies, skinning away and humming to himself. For some reason, that makes me just see red. There are lots of other places he can farm skinning, so why does he feel the need to gank my quest mobs? It makes me seethe just thinking about it!
Unfortunately, as Nikol finds out, there is no set etiquette-- outside of a group, it literally is a free-for-all. If you're in my place, your only real option is to just find another quest to work on while all the mobs respawn, or poke around to see if he missed any. And to tell the truth, I shouldn't get so angry anyway-- it could be that the mage didn't realize I needed those pigs, and in fact, there is probably a whole other cache of pigs just over the hill that I haven't found yet.
But for some reason it just drives me nuts. Have you been on either side of this situation? And how have you handled it?
