What shits me the most is you are the last to join the group and the first to reach the stone while everyone else sits around in Dal with a thumb up their backside like it doesn't take two to summon.
I always try to get to the instance myself. With the number of flight paths, and flying finally added, it doesn't take long at all.
Seriously, I think the hardest one to get to is Dark Heart Thicket, and even that takes hardly any time at all.
