I think you misunderstood my comment. It wasn't about the speed of EXP but rather the reason why people don't queue for lvl 60 dungeons.
Being in the largest guild doesn't mean you'll find people with the same interests. Yesterday I ran 5x lvl 60 dungeons for MSQ and achievements WITH guild members.
Of course - the server's stabilty and the reason you cannot use party finder an the moment make it difficult. That said, it's not impossible when you find same-minded people.
It is the other way around: the hardest part is always to find people. Awakening is even worse in that.
