GoD was a bit of a funny expansion too. Many, many people saw little point in it. Although for a serious raiding guild it does seem the logical way to go
after PoP. That is a part of the problem, if you haven't finished PoP progression then requiring people to have an expansion they may not see any use for would be divisive.
PoP was really a no-brainer with it's raid functions (at last) and rapid transit. There was little reaon for anyone involved in a raid guild to refuse to get it.
LoY was a bit more marginal. There was not that much in there for a guild engaged in Velius, Luclin or PoP progression except some gee-whiz things and a couple of recreational raids.
LDoN was almost raid-irrelevant unless you had the kind of force to do LDoN raids. In many ways it worked against raiding guilds, certainly their ability to spontaneously raid race targets.
GoD explicitly adds high end content and some very nice drops. It also has it's own raid progression which in difficulty appears (to a lowbie like me) to follow on from PoP. I can well see how a guild heavily involved in planar progression would not want to divert effort into it.
That said it is not exactly an expensive buy. If having or not having it are breaking up your guild then it implies undelying issues for which this is being used as an excuse.
I think EQ has been hurt by the number of new games but it has recovered pretty well each time. Lots of people went to Horizons and came back, to SWG and came back, to Lineage 2 and came back. I suspect that lots will go to WoW and come back. It is even likely that many will go to EQ2 and come back.
I'll let a techie correct me if I'm wrong but I don't think there is a direct link between game server numbers and physical server numbers. In other words an EQ "Server" might be one cluster or there might be several "Servers" within that cluster. If I am right then actual server numbers is no indication of the game's health since if the same hardware can run two or more virtual servers there is no difficulty or oncost in them opening new servers on existing hardware. Shoot me down you SA's
However if subscriber numbers were falling seriously then we would be seeing zones clearing and overcrowding disappearing. If that were happening I doubt they would create more game servers to spread the playerbase even thinner.
I think Jennock has a good point too.
The spring is sprung,
The grass is ris,
I wonder where my guildies is.
