I'm not sure I am qualified to post about playing a DPS, but then again - that never stopped my opinion before, so why start now. I did notice a few interesting aspects about DPSing ... partly while playing one myself and partly while tanking heroics and raids.
I think Blizzard did a surprisingly good job of making the DPS job more challenging and more important. I'm also surprised at how well very different philosophies predicted this. Examples? Greedy Goblin stated in April 2010 that DPS would be the new critical role, Righteous Orbs (Chastity, in this case) predicted it to be the new "cool" role in July 2010.
And they were all right (especially those I didn't link - and I'm sure there are many more posts like this). Of course they were, because all bloggers are secretly part of an illuminated society and do know about everything in advance.
Back to the topic at hand, though...
There were a few subtle (and not so subtle) hints that DPS nowadays have to take a more active role in their own survival. The odds of getting killed outright have been reduced somewhat (in appropriate content), but at the same time you're not guaranteed healer attention any more. In the words of my wife: "If you draw aggro with your Bladestorm, you're on your own, buddy. I've no mana to waste on sponges like you!"
Do you know where all your heal buttons are? I still forget about them - healthstones, potions, victory rush procs, enraged regeneration, bandages ... are there more for warriors? Probably....
On the other hand are the DPS checks. There are quite a few in raiding content. We have so far run into two - one being Argaloth in Baradin Hold, the other being Maloriak in Blackwing Descent. One of them is a single target DPS check (70k damage required for the whole raid (10) over 5 minutes), the other an AoE damage check (kill 315k health abominations within 15 seconds - damage is doubled, though). And occasionally, my groups fail.
This is something that can partially be improved with gear, of course. More shiny stats will improve general damage output and survivability at the same time. But the general issue remains - DPS have to be good this expansion.
I like it.
This is not enough. The old "DPS really needs to be above tanks" is still true. Possibly even more so now than it was before. In hard content, the speed of the kill matters.
