While talking to a ranger I met during the monk "strike" (read: party), we started discussing some of the more annoying things that can happen while you're monking. I pointed out one of my major pet peeves was aggro management--and that, for instance, a party does -not- need three different people charging aggro. Aggro management can be.. well.. managed much more efficiently if ONE person charges aggro (one person, no doubt, who is buffed), gains it, and then the rest of the people fall in.
Well, after saying this, Vevila Gray (the ranger), made this suggestion: It'd be nice if Anet made an Aggro Management Training Area (to paraphrase).
And I realized, hey, that's not a bad idea. They have all these other training areas. Why not have an area emphasizing the value of good aggro management?

It doesn't even have to be obvious.
It could be hidden in the confines of a more enjoyable mission or area.
Sort of like how they snuck those amazing stance tanks into Black Hole.
