Tank Training

[Bustercucumbers]

Also, there's the issue with Flash. You have a quest that teaches you that Flash actually allows you to grab AoE aggro. You NEED to use it because the NPC will take a beating otherwise. Apparently when some people finish the quest the knowledge they acquired just vanishes from their minds..
More quests to teach the players are useless if the players are not willing to be taught..

Pretty much this. I've met so many stubborn players. Another thing that doesn't help is that Fate grinding is the easiest way to level. You aren't going to learn proper tanking from something that rewards zerging and mass chaos.
