Desolation EU is high population as well, but let's be honest. Most people prefer and teleport to the human starting area because it's nice looking, easy to complete, and does not require you to go back and forth too much ( like in the case of the charr starting area ). Also, generally speaking, the events are easier and faster to complete, they activate more often, at least from my experience.
I'm still undecided if to keep staying on desolation, or to move on some other realm ( even though I have reached almost 80 with my charr warrior )
