People vastly over estimate the amount of “pugging” that will be done in vanilla with how raid lockouts work…
20 mans, and onyxia fine, but pugging BWL is impossible and even MC is going to be beyond most pugs just because of how long it will take to get everyone through it.
People will leave 2 bosses in because of some reason or another… and you’ll have to send someone out to town to find more… then run a warlock and two others out to summon them…Then wait, trash respawned…
Now more people leave because you have to reclear trash…
As you finish more and more of the instance it’s harder and harder to replace people, because they don’t want to do “half of a run” and miss out on loot opportunities…
One of your tanks leaves right after Garr because it didn’t drop the binding he needed
5 hours later, you don’t have teh people to do Ragnaros, can’t fill the raid because people don’t want to skip most of the bosses and get saved just to rag, particularly when it doesn’t even look like you can fill the group back up…
Absolutely no one will ever log on to finish the raid at a later time (if they could manage logging on more than once per week at a set time, they’d just be in a guild)… and the people who only wanted ragnaros will realize that joining this raid just wasted their weekly lockout and 5 hours of their lives and never run with you again.
Also, it’s going to take you at least 2 hours to form up, because you need to make sure people have essences, gear, aren’t specced like morons, have fire resist, and appropriate consumables before you start.
“pugging” raids in vanilla is more or less a myth. You’ll do 20mans, and Onyxia (and only because ony is a single boss so you don’t get saved if the group is a failure)… BWL is almost entirely out start to finish… Maybe AQ40 gets a few bosses.
Pug MC runs are almost entirely done with guild alts, half guild runs carrying randoms (and reserving bindings for their tanks that still needed), or people otherwise thoroughly vetted/verified to the point where they probably could be considered an informal guild on their own.
