I was playing PvP with a bunch of random people, and they were not doing the best at PvP. The were being impatient and spamming that left click button. So I thought that it would be good to have a tutorial that could show players, old and new, how to use the new PvP functions from 1.9. I think it would be something like when you join the lobby, you could have a link that could take you to a video before you join a game. Or even an armor stand that would give you a link, I don't think a tutorial like in any other way would be very effective, besides practice of course.
