I don't think warriors need more sustained AE threat. You have Incite + Deep Wounds for Thunderclap and also Shockwave. Maintaining threat is supposed to take some effort. I don't think tanking would be any more fun if you hit Tclap and never had to hit a button again.

The actual problem, in our minds, is threat scaling. Warriors (and all tanks) could AE tank just fine in Naxxramas.* It only became a problem over time when the dps of the dps classes grew so much more quickly than the tanks, largely because the dps classes have so many dps stats on their gear while plate tanks have Strength. Tank damage was pretty close to 50% of dps damage in the first tier of content, which was our goal, but has slipped to 25 to 30% of dps (your mileage may vary) in Icecrown.

We need a system that keeps tank damage scaling at the same rate as dps damage. However, that system can't be dependent on gear stats (unless you're willing to see tank gear go away) and can't be as ridiculous as deep talents that say "You get 5 AP per point of Strength."

I think you just notice threat issues more on AE pulls because things like Tricks and Misdirect mask any problems on single target pulls. Separate problem.

And yes Paladin tank AE damage and threat generation is still too high, largely because of Seals and HoR, but long-term we're going to nerf that instead of making all tanks able to trivially maintain threat in all situations. Referencing the other thread on threat a little, why as a tank would you even care what buttons you push if maintaining threat is a foregone conclusion?

* - AE tanking was fine in Naxxramas. AE damage was, and has remained, over the top. We prefer a model where the risk of tanking too many mobs is that the tank dies, not that you can't maintain threat on them all (within reasonable limits of course). We also prefer a model where the dps do AE damage on some pulls and switch to single target dps on others.

(...) Yes, you're balanced around it. Yes, I can read the tooltip on the talents. I'm saying the solution, in our minds, is not "I hit Thunderclap and it autocrits, applies Rend to everyone and then ticks for 10,000 K for the next 30 minutes." We might as well just remove the cooldown from Challenging Shout if that's how Tclap is going to play.

Dude pulled aggro does not represent a failure of class design any more than you sometimes dying represents a failure of class design. Both are going to happen sometimes unless you're absolutely at the top of your game. That's part of the challenge of playing your role. For our part, we'll make sure you have the tools to do your job, and for the most part you do. I don't think the tools are the issue, as I said above.

I'm talking philosophy here, because I assume that's usually more interesting to a wider audience. Philosophically, tank threat generation is working correctly (i.e. as we intend) with perhaps 4-5 exceptions that we would like to fix:

1) Paladins can do a little too much AE tanking "splash" damage, often without even setting out to do so.
2) Tricks and MD take too much of a burden off of the tank / hide issue #3.
3) Damage and therefore threat generation aren't scaling well at very high levels of gear. <-- this is the big one.
4) There is too much incentive to AE every pull, which puts a burden on the tank to AE tank every pull.
5) You could probably add that bears need a button to hit besides Swipe.
