1hour shift is best for east coast, 2hour shift is best for west coast so why not meet in the middle and do a 1 1/2 hour shift to siege OR make both available to siege in. Durng siege signups guilds could choose either 9pm eastern or 10pm eastern siege slot. Which ever works best for their guild. We don't need siege times every 4 hours like the current setup. Just a choice between 9pm and 10pm would be a lot better.
Somehow, I don't think they can do a 1.5 hour shift.
Let's go back to the old saying, "Be careful what you ask for." For a number of years people have been asking for two Siege times per day. Well, I think that GF and RW, in an attempt to make Siege available to anyone at just about any time, came up with the idea of 6 possible Siege times per day, every four hours. Nice idea, but the actual implementation hasn't quite worked out as well as they wanted it to. Not to mention that allowing guilds to war against each other *outside* of a "registered" Siege time has allowed guilds to "game" the system, drop points (which should *never* have been allowed in the first damned place), and be able to Siege against less-able and less-capable guilds. This allows the "better" guild to gain BoTs and Honor Points more easily. Poor design, that. And, of course, off-topic for the purposes of this discussion. My apologies.
As Mika has stated, he's not sure if it's technically possible to shift or move the current Siege/Guild War times. That idea may well depend on when the daily "reset" for determining when a guild can register for Siege (*not* an "Organized Guild War"--those are completely different). That has yet to be discovered and I agree with him that the current status quo should be maintained until he can get and report further information from the tech people.
Now, *if* the shift can be done so that guilds can only register once per day for Siege, then that's a Good Thing. I'd prefer that what is now the 12am (EDT) Siege slot be shifted back two hours to 10pm EDT. Why? That has been the "traditional" Siege time slot since Siege began back in Chapter 2. While there are some people who cannot and will not be easily able to take part in Siege at that time, it is, in my opinion, the best compromise time for the vast majority of the players located in the continental US, Canada, and Central America. I mean no offense towards people like GarySandstorm or Murlakiel, who are located in South Africa and Brazil, respectively. But...they are representative of the relatively small handful of players on the US servers who are either in very different world time zones or, in Murlakiel's case, located in a time zone that's one hour ahead of the US Eastern time zone.
My two-cents' worth.
