Well, it's time for a big reaction thread and since noone else has started one yet I'll go first.
I only played one level after getting the patch so far: the MH-60R demo. I have to say that the hydrophone dipping is back on my list of things to do. I love the speed that it drops and comes back, it makes dipping much less hazardous though you have to be careful not to run the hydrophone into the ground in littoral waters. Other than that, watch out you don't even move when within 10 miles of me.
I'll test out the P-3 and the rest of the MH-60 systems but if this is all they did, then I'm happy.
