Why is everyone that I group with either attacking separate targets, or the toughest ones? Is it in their mindset that this is the best solution? As a Tank, every time I join a group of PUGs I end up having to explain to them, please kill the weakest one first and then the stronger ones. But they don't listen, and the healer and tank have to struggle a bit.
It's not terrible, it doesn't lead to wipes in normal mode, but oh man are these folks going to have hard time in heroics later, and in their class stories and solo.
