In addition to every theorycrafting source saying we've been buffed by 1000+ DPS (more than we necessarily needed), I've seen parses of feral druids performing well all over the place. One example is:
Raid History
Disclaimer: I don't know Premonition or Darthn (name seems familiar on the boards), nor do I know much about the PTR fights, so I can't say one is more movement-intensive than the next. But across a range of fights, Darthn does VERY well in a lot of fights compared to other melee DPS.
Wow Web Stats
Here's a parse from Juggernaut, Kazanomnom was 2nd to a warlock in DPS (not total damage, but he had 73% presence). Again, I have no personal knowledge of the guild, player, or fight, so take it for what it's worth.
I'm not going to make the claim that feral DPS should be lower than other melee DPS, but we certainly don't deserve to be significantly higher than the warrior/dk/retpally/etc DPS.
These were both pulled from the official WoW forums-- Premonition is the most discussed guild, since their resources are consistently updated in one place, and made Patch tank/DPS testing a priority, so that may skew perceptions a bit.
Angi, those are very particular fights that I'm not sure should count. Not many bosses have enemies that die under 15 seconds but can't be AOE'd (where cat swipe is great); not many bosses have enemies that go immune in the middle of attacking them. A LOT of bosses ask you to stand still and attack, or chase and attack continuously. Even the fights that do have those mechanics, have them alternating with the tank-and-spank type mechanic.
