So who's going to teach us how to do 3.1 content? It is no ones job to teach players anything. It's the player who wants/needs help's (don't care if grammar is wrong here) job to make the effort to better themselves. Not someone who is experienced to snap and then tell them what they should be doing.
If a player chooses not to read the tool tips for their job or figure out how mechanics work after the first wipe, then there is a very high chance that same player will not listen to any given advice the community may give them, if anyone were to try.
