I voted Horde but I don't mind either way. I'm not even sure how it pans out if you're in an active raiding guild because I have no idea how many in my guild will play and raid in classic.
If raiding is going to be easy enough that we can clear most of it with 25-30 people, then you should be able to accommodate some of the more casuals that would like to raid. We're all too old for weepy drama BS and peoples' feelings getting hurt if you're up front about how it's going to be from the beginning:
- Did you put in time to do your attunements?
- Did you watch strat videos and understand what is expected of you?
- Are you okay speccing to Resto and not getting to play Feral Kitty Raiding Adventures? (At least not right away, once we're all geared up we can cover the gaps and let people raid offspec).
- We try to be fair, but do you understand you are entirely at our mercy in terms of what loot you will get? In order for the core raiders to make it possible for you to experience this raid, they need to get their upgrades first. However, there are multiple pieces of loot they don't need, and you will get upgrades because it's better than letting it rot.
- Do you understand that if you are not going to be a committed raider, we may ask you to sit some days to make room for other casual raiders or for raid comp purposes? The core of 30-35 can only carry 4-5 people. We will try our best to be fair and get people in as best we can, but you will have to rotate out to make room for your guildmates.
The hardcore people shouldn't have a problem letting a few casuals rotate in while raids are on farm to collect loot that might rot. The casual people shouldn't have a problem if they're being treated fairly, and they also know they can apply to be a committed raider if they're willing to make the sacrifices.
