As others like fastboy said, there are already guilds doing this, like one I am in on Trakanon:
Lost In Progression
We are going through all eras, and recently opened Luclin. Most new folks are raid-ready in a few days to a week, since our goal now is to make it easy to join us raiding by using mercs to catch up rather than disallow them and make well-intended people quit.
Many of the rules mentioned we do follow, with some practical exceptions.
- we use PoK, AAs to current cap b/c it isn't worth trying to police things like that (and w/o EQPlayers, Magelo or a tool like my old guild Wrathful Inquisition used to have, there is no way to make it easy or fair)
- we use mercs to level (but prefer guild grouping), and never for raid or epic content unless it is on group-farm status
- we sometimes use high-level unguilded alts to check on non-instanced raid content availability, so we don't waste a night just looking for something in-era to kill (until Time B anyway)
- no ooe gear or zones, that we do check on
- we just opened up Luclin mounts (but no stats or market mounts)
- we have each era's criteria for advancing to the next era mapped out in a list before we begin it (like all nameds, events, keying, epics we want to do, including how many times minimum, whether whole guild or at least one member does it, etc.)
- we vote on everything, like when to unlock once criteria met, policy changes, etc.
- we round out raid force with alts if needed
- most members are veterans of many eras (classic through Deathknell is common)
- the main goal is to experience all the raid content of each era, while maintaining in-era rules and conventions as much as is possible (and practical) given the current EQ state.
Even though we know the fights, sticking to the most important era limitations makes for interesting if not challenging content. Sure, we waltz through some things, but we can also wipe to others. And we are only in Luclin, which everyone knows doesn't have the relative difficulty of PoP, GoD or OoW onward. The OP factor lessens as the eras do.
I would recommend taking a look at our site or talk to someone in-game before trying to start another progression guild up.
