spread out your people are and what days they can raid on. We are mostly casual players with on 3 to 4 serious days a week to play. For us it will come down to having enough people keyed that match a schedule of when they can commit 3 days to
While we're not a medium guild (large actually), we realized somethings very quickly.
1) Every group needs at least 2 tanks (preferably Warriors).
2) Sadly, due to size, not everyone gets to raid regularly. Therefore, we actually have set "key" teams, and sub-in non-team members as needed. This will change as we progress... namely, as Attunmen, Morose and Maiden stop dropping desireable gear for our teams, we can start to sub-in non team members so they can begin to get their feet wet and start to gear up.
We have 3 groups, based on our healer and tank mixed. Teams were formed less on gear requirements, and more on reliability of the players (i.e. skill, and showing up on time and prepared).
While there has been a little conflicts, so far we've managed. We had a "prime" team formed with about 3/4ths previously non-prime members. It worked out cause the team is dedicated, prepared and has learned to play well together.
Truthfully, we don't have subs for that team. There are 10 people (2 of which have lvl 70 alts). Our team is made up of:
1) Warrior Tank
2) Warrior Tank
3) Fire Mage
4) Shadow Priest
5) Holy Paladin
6) Holy Paladin
7) Holy/Disc Priest (with Frost Mage alt)
8) Resto Druid (With solid Balance gear too)
9) MM Hunter (with Rogue alt)
10)MM Hunter
To be quite honest, we don't really ever have need of the Rogue or Frost Mage alts. We just don't use them, though they are there should we. We've currently cleared up to Chess in 4 hours, and have it on farm status (Attun, Morose, Maiden, Opera, Curator, Chess). However, we haven't begun trying Shade, Illhoof, or any of the other bosses after Curator. (Moving on to Shade this week)
This leaves a lot of solid players in our guild to form at least 2 other groups, based on the number of healers and tanks.
Once again, the way we handle it is we have set "teams" with the rest of the guild understanding that if they are ready and prepared, they might be subbed should a team-member not be able to make it. Usually at least 2 subs happen over the course of the week. It's helpful to explain to the rest of the guild, that as we progress, the earlier bosses will become available to new players, as we'll begin to sub-in those players for the initial clearing, and have the prime members return to continue progress the following scheduled run, picking up wherever they left off on night one.
Of course, as soon as you get more of the appropriate classes, you can begin to form additional teams.
Anyway, set teams with everyone else being "subs". That's the way we handle it.
