Now that's a little harsh :)

I'd say this is debatable.  If you can't trust the clients, how do
you gain by offloading processing onto them?

So you're saying that they don't enforce action timing on the
servers but instead rely completely on the client-side animations as
a timing mechanism? This sounds like a poor design decision.

Well, I've already said my part about this then :p It may reduce the
amount of server processing, but it's a poor tradeoff IMO.  Nothing
should be given client-side control that can give one player an
unfair advantage over another.  I'd rule this as a regrettable
design flaw.

I was basing my statements on the assumption that AC was designed in
a way that makes sense. I'm a career programmer and I do a lot of
network programming, so it's not exactly like I'm completely talking
out my ass.  Perhaps you should be a bit more politic in your
criticisms.  There's no reason to get nasty.

I suppose that over the course of a few minutes this should be
detectable.  Though it would have to be carefully tuned to not flag
people who were merely victoims of lag bubbles.  Still, it still
seems like a band-aid for a poor design decision.  With any luck,
AC2 won't have a similar problem.
