Did I say that? No. But at least they would basically know what's coming! At least they made an effort! They didn't just turn up and basically say, hey, I didn't bother doing any research at all, please spend your free time explaining mechanics I could have had the decency to read up on myself!

What's the difference between watching a video and getting people in duty to explain stuff to you personally? TIME.

By not doing so you are basically saying your time is more important that that of seven other people.

And yeah, I think that's rude, so make some personal effort. I don't mind helping those who are trying and are willing to learn. Unfortunately the majority like to stay silent and pretend it's not them that's new.
