Haven't played too much since the patch hit yet, so can't comment too much, though did do a CoS pug earlier.
So far, ES feels about the same for me, though early WWS logs suggest a rise of close to 2k DPS since pre-patch, among Naxx Hunters.
If the 30 second Lock and Load CD is there, it's silent. I also didn't notice it on single targets, since I generally take around 30 seconds per kill on single mobs anyway. There is no visible icon when it goes off, if it does, either.
I'm still here, and will be going back into the game after writing this to do some Heroics. There is hysteria among BM Hunters on the forum at the moment, although that is predictable.
I can't give Santyn those ArkInv rules I owe him yet, either; because AI has apparently been messed up by the patch. It's maintenance was shaky before 3.0.8 as it was, so I hope someone will come forward to pick it up.
I am staying.
