The problem is that Isle of Quel'Danas was made with population CAP of 2495 in place, and in mind.
If stats are correct, we have anywhere from 4-8 times that online at any one time.. However, mob respawn isn't buffed, Sentries aren't buffed to compensate for the ridiculous amount of ganking occuring (They should be able to kill players, however currently there is so much ganking going on that they literally hit nobody, ever).
Currently Isle of Quel'Danas is nothing but being ganked by multiboxers and/or 40 man raids. Congratulations, you've turned TBC into a bad Vanilla server.
Things need to be changed. People actually want to play the content, not be farmed by a sad runt on a 15 shaman multibox in the only hut that gives quests.
