Here's the real deal, speaking as someone who has given A LOT of non-clear people a chance to sub in for my static, as we have been perpetually missing one DPS for about 3 months.
In the beginning, I was willing to let just about anyone who could type in full sentences into the group, as long as they could take direction. I gave pretty much everyone a chance. This led to hours per week or wiping because people were A. Not as good as they thought, B. Not as good as they said, or C. Totally non-committal to learning.
This was unacceptable because my raid group has 6 hours a week to raid, and we already spent the time learning the fights. We were down to actually doing new stuff for about 2 hours per week.
Next, I would allow people in with experience on at least 1/2 of the fight. Hey, they learned that much PUGing, they can probably learn the rest in a few wipes. Nope. A lot of the same issues: not correcting their mistakes, not paying attention to mechanics, not understanding what to do. Again, hours were wasted.
This was unacceptable because of the same reasons. My static members were getting frustrated, I was getting frustrated. I tried to be kind and patient but the PUGs, by and large, were unrepentant, quiet, and unskilled. I'll stop here to say that we did find some really good players PUGing, mostly people that had missed their statics. I'd say about 5% of the PUGs we got that weren't already in a static that they had missed were acceptable. Those people are now in my static. I'd say our success rate for PUGs was roughly 20% overall.
That 20% success rate has conditioned me to reject people that send me a tell saying, "I watched the vid, so I know the fight," or people that say, "haven't ever been in, and don't have teamspeak, but I'm a fast learner!" I have 2 hours to clear my fights for the night, if I have to spend an hour teaching you something and letting you get used to it, you have just taken 50% of the raid time away from 7 other people.
Anyways - Next, I only allowed players with experience on the full fight, "I've been to 5%" was an acceptable answer. This dramatically increased our clear success rate. We got NUMEROUS people their first T6 7 and 8 clears. This is acceptable, and is currently what I allow.
Here is the deal - most "elitist raiders" have put in the hours to learn these fights already. Because of that, my motivation to go back to the phases of fights that I have been in dozens of times while learning myself and helping my static members learn is unbelievably low. I set aside time each week to raid on a progression basis; it is for ME. That is my time to play the game I like in a fashion that I enjoy.
Would I be better off if I took time out specifically to teach people the fights and get them a clear? With the amount of time I play, and most of my fellow raiders play, almost definitely not. The chances that after I help you learn and clear a fight that you will come help my group clear the next fight, or fill in for us another night are extremely low. Especially getting a proportionate amount of benefit from you knowing that fight to the time we lost teaching you.
I'll tell you what, I will teach you all of SCoB up to Divebombs in T9 (because that's where my group is), if you sign a contract saying that you will be available to fill in for my group 40% of the time if I need you to be there, no guarantees on slots. I will e-mail you your "on-call" schedule at the beginning of every month.
You have to understand, teaching someone SCoB is frustrating. Its hard work, and it feels like walking through quicksand. Think about if I asked you to help me craft some items. If that takes 5 minutes I'm very sure that you would jump to it and help me out, maybe even for no cost and you wouldn't charge me for mats! Thanks man. Oh yeah, I need TWELVE TIMES this many items!
You don't have time to craft something trivial for an hour for me? You. Elitist. Scum.
