I'm also very casual but I do feel we should be personable responsible for knowing the generally accepted strategy. That information can be obtained before you try to raid.

Now, on the other shoe, I won't join such groups that insist on stupid things like unreasonably high GS (such that you need no loot from those bosses), or things like that. And further, "must know fights" is a sign of raid leader laziness. Its indicative that they have no clue how to teach, or no desire to teach. That's pretty much a main qualification of the RL, in addition to putting the raid together and handling loot. Yes I know being RL is a burden, but somebody has to do it; likewise you have to start somewhere. Take a look at the applicants armory. Any PVP gear? bad enchants/gems? If so, probably not a good fit. You can also see what kind of drops they got, is it all badge gear or some ICC? That's a bonus for you, since that means they do know how to kill the boss. It isn't a crushing burden to look at the armory for everyone and use your brain to figure out if people are a good fit or now, and it avoids the whole GS nonsense.
