I'm not sure if this is a request for Blizz to include, or if its a question to the readers to see if this already exists in some form or another. Any hoo, here it is...
I would love it if there was an instance a 5-man group could go to that is pretty much purely for practicing keeping aggro on a tank. I'm talking about a dungeon that has very little trash to deal with, very little complex pulls (or any pulls besides bosses). I don't care about loot in here.
Just a series of bosses that add in a twist as you get to each next one. And either Blizz or some third party could write up suggested "lesson plans" for a team to run through.
First boss - just a total tank and spank. One mob, no adds. Very little movement or special attacks. Only attacks 1 target, the highest on his threat list. His hits are moderate in strength, but he's got tons of health. The purpose of this guy is to allow a team of 5 (or maybe more, but I want to start basic) to practice the most basic threat management skills in a very simple environment. The lesson plan for this guy could include ideas about allowing the tank to solidify aggro before DPS goes nuclear. Perhaps a Q&A review at the end where the team asks itself "did anybody besides the tank take any damage during the fight?" Since its a hugely simplified environment, just for practice purposes, that should be feasible, unlike real instances where there is much more complexity.
Second boss - Similar boss to first fight, but some relatively weak adds show up.
Third boss - Maybe mix in an attack that will stun the first person on the threat list and switch attack to the second person on the threat list.
Fourth boss - Add in some movement or terrain complexity.
And so on.
Is this just something that a player and team of players just sort of go through during normal instancing? My experience has been that the instances start you off with just a hair too much complexity to allow n00bs like me to really build strong fundamentals.
Maybe it'll just come with time and repetition with the same players, and good communication with those players.
This past weekend was the first time I've ever had a party with other players who use a threat meter. Up to this point, its only been me and my pet on the meter. Now that I'm running more instances in Outlands, many or even all the other players are also running a meter, so my Omen shows a big chunk of the party. Funny, because on one run, everybody except the tank had it installed, making it pretty useless :-)
Being new to seeing other players on my meter, I was not really able to pay attention to the meter, plus chain trap a mob, plus try to keep pouring DPS on the proper targets according to our specified targeting order. Lots of data to process and adapt and react to. I'm hoping that it'll just come with time and practice. And that's what spurred the idea in my head of a hugely simplified environment to allow a team to do a doggy paddle in the kiddy pool first, rather than plunging into the pool to learn to swim.
