I'm on a high end as well, and next to no latency so I'm in that same boat as well. The only times I really notice anything in the slighted is when lag seems to hit or when the AT&T jumps are foobaring things. At this point that is what I'm really suspect of, but as I don't have the code, I can't be certain nor test it. I really wish the devs could 'fake the net' in their dev lab. I mean it shouldn't be that hard to fake internet hops, induce delay, and packet drops that are never reported back.
I don't think things ever got fixed so much as improved though.
What I really wish our ranged attacks were given is the leading AI for shooting that mobs have.
