Whoa there tiger, why not get off your high horse.
Instancing in MMOs is a very personal taste thing, some people dont mind it, others hate it.
As for your dodging, sidesteping and so forth, AC did all that in a non instanced world, in 1999. So yes, it can be done with thousands of people in the same area without latencies skyrocketing exponentially. (and in AC you could dodge arrows and spells by sidesteping/dodging too)
Why not just accept that some people dont mind MMOs with instancing (like the people who still today play DDO and CoH), whilst others really dont like instancing at all (like the people still playing UO and Daoc), instead of getting all worked up and capitalising stuff.
Its far too early at this stage to say whether AoC will be a success or whether it will be a failure, only time will tell on that. We do know that they have 400,000 accounts at the moment (although a poll this week on whether or not people would stay after the free month showed that 53% were not sure they would or definately wouldnt), perhaps AoC will grow and be an immense success, perhaps people will reach level 80 in a few weeks and decide that theres nothing really to do (a la DDO) who knows, at this stage nobody knows. All we can do is wait and see, and see if people are still raving about AoC in December.
Hehe, sorry, didn't mean to sound like a rabid fanboi, I certainly don't "like" instancing for the sake of it, I just realise it's there for a technical reason and it's not a design decision. I haven't played AC, though I was still on 33.6kbps back then so I doubt *I* could dodge arrows by sidestepping if I were playing it!

It's simply inevitable that, the greater the number of players connected to a server simultaneously, the greater the latency - hence back in '99 when I launched up Quake III and looked for a game of TDM or CTF every server I'd see would give me unplayable pings of 300+, whereas if I looked for Rocket Arena games (1v1 or 2v2) I could, with luck, coax my crappy connection into getting a <200 ping.
Good coding can help with this, as must have been the case in AC from what you describe, but there are limits. Hence if you have a non-instanced world like WoW with hundreds of players simultaneously connected to each zone, latencies will be higher than in a game like Guild Wars, where everything is instanced and the most you'd ever get in a PvP match would be 48 players (and that was back when it was first released when you had an 8v8v8v8v8v8 map in Tombs). The average latency dictates the style of the gameplay, which is much faster-paced in GW than in WoW - in the latter 3-5" activation times for skills are common, whereas in GW they are rare, most skills activating in 1-2". Many interrupt skills in GW had a casting time of 0.25", and skilled players were expected to be able to interrupt spells with 0.75" cast times - something I could never do!

Assuming a reaction time of 0.25" (which is faster than average, but that's what a skilled mesmer in GW would have), a ping of 50ms or less would be necessary for people to be able to reliably get those interrupts to work (and damn me did they ever, they were my bane as a monk!

), something which would not be easily achievable in a world with as many simultaneous users as WoW's. I had a guy in my guild who played a monk back in the days when spike teams were rampant, and he did well even though he was on a dial-up connection IN POLAND! I don't think he could've done that in any other online game tbh!
I'd love it if one day everyone had fantastic low-latency broadband so that developers could build massive, detailed worlds without worrying about overpopulation causing lag, but until that day everyone has to compromise - Blizzard compromised by making the gameplay slower so everyones' connection could keep up, Funcom compromised by making Conan instanced so you don't have ridiculous numbers of people all in the same area. Personally, I'll take the faster, more actiony gameplay over the increased "immersiveness", because the latter tends to go out the window as soon as I see someone called IPWNZU bunnyhop past me shouting "LOLZ!!!1" anyway!
And, btw, it's not a high horse, it's a mammoth!
