One reason I was originally hesitant to join a guild in Classic was that I was worried that I might end up liking it too much, leading to me wanting to spend more time in game than I realistically have available for this particular endeavour. This pretty much happened. D'oh! I sort of already wrote about it back in October, though I focused on the pull of wanting to be social with my guildies back then. However, another dimension that I haven't really talked about is that - once you get into the group content - it feels like there's just so much to do in Classic at max level, especially right now.
I've often expressed my disdain for the way Blizzard changed retail WoW to basically always be just about the latest patch, with any and all content from previous patches being obsoleted almost instantly unless you're into farming cosmetics. I will admit though that I hadn't considered just how exhausting it could be to on the other hand have everything be relevant to your power progression almost forever.
Just looking at the raids, Classic WoW has six of them at this stage of the game, with all the original content released: Molten Core, Blackwing Lair, Zul'Gurub, Ruins and Temple of Ahn'qiraj, and finally, Naxxramas. You'd think that if you're clearing most of Naxx, there wouldn't really be any reason to go back to any of the older raids unless you want to gear up an alt or something, right? Weeeell...
Molten Core is probably the closest to being truly "obsolete" at this point except for fresh sixties, however the legendary Thunderfury remains alluring, giving warriors in particular a reason to keep dragging everyone else through the place regardless.
Blackwing Lair drops some much better pieces of gear than MC, but still, most of them are superseded by Naxx gear, right? Again, weeeell... most of them, but there are some rare trinket drops that are Classic best in slot forever, giving people chasing their BiS incentive to keep coming back for a shot at those rare drops if nothing else.
Zul'Gurub was introduced as a smaller-sized catch-up raid for fresh sixties, so you'd think it would be in a similar position as Molten Core by now, but something that I didn't immediately realise was that it's also the source of the only real worthwhile enchants for the head, shoulder and leg slots. Head and legs require idols, of which you can only ever get two per run. Shoulders require exalted reputation as well as a lot of tokens farmed from trash drops. Basically, have fun farming this place forever until you've got your final BiS and got lucky with rolls often enough to enchant it all.
AQ20 is another easy raid in a similar vein as Zul'Gurub, but here the perpetual draw is that it drops max-rank spell books for three spells for all classes. At least these can be traded between players, so you don't necessarily have to go there yourself to get them all, but someone's got to keep running the place to supply the market. Those books don't appear out of thin air.
AQ40, being the last raid before Naxx, is another interesting one because while for some classes it's pretty pointless to go there if they can get Naxx gear instead, there are sets in there for certain classes and specs that don't really get superseded by anything else, meaning you'll have a particular niche of your raiders forever clamouring to re-visit this raid as well. I guess I've got to give those Vanilla game designers credit for succeeding at keeping players interested in all the raids.
Now, lest you get the wrong idea, I'm not actually raiding all these places every week, and neither does my guild as a whole. We haven't been to MC since just before Naxx release for example. But everything else... people do go back to at least sometimes, and I in turn feel a certain pressure to come along if I can, both to work on still improving my pally's gear to help with our Naxx progression but also just to simply help make up the numbers.
So in addition to everything else I'm now actually also looking forward to Burning Crusade for the simple reason that we'll only have one tier to work on to begin with, leaving a lot more "free" time to spend on alts or dungeoneering. And any character copies that I keep on original Classic realms will simply have forever to achieve their goals there, with no more changes coming after that. I guess right now there's just a sort of unique pressure to "finish off" as much as we can, as anything achieved now will benefit both characters moving forward into Classic BC and those staying in the Vanilla world.
