I'm pretty sure a lot of people already noticed this, but the "event" and "objective" sound effects in Deepwind Gorge are reversed. As an alliance player, when horde attacks a flag controlled by alliance, it plays the sound effect normally associated with alliance taking a horde flag...which means that if alliance is losing control of the map (bad) it sounds like you are gaining control of it (sounds good, but still is bad).
Same deal when grabbing a mine cart - if horde takes alliance mine cart, it plays the sound it should play when alliance is taking horde cart and vice versa.
I may also be in a small minority, but I rely on auditory cues as well as visual to clue me into the best way to help my team win. It would be nice if they fixed the sound effects and I'm not sure if this is an alliance-only problem or if the same issue exists horde side.
