The word you're looking for is 'Conqueror'

it would do only that you will need to wait for tank even longer :)

I dont have any problem with boring HC, they are not boring? Are they easy? Yeah, they are much more easy since I dinged 80 with my first char in blue :) It was like 40 min or more for one run.
Is it boring now? No! I try to run trough them fast as possible - range is 10-20 min depending in group and HC. Runing them slowly can be boring - but they have so much challenge how you want :) Just do bigger and bigger pulls for faster and faster runs trough :)
Addons like InstanceTime will show you how fast you are :)

When the whole heroic mode idea came out, and the whole tiered badge thing started, I said from the beginning that there should be...

Heroic
Valorous
Conqueror
Triumphant
and... Frosty? hmmm...

Levels of difficulty for heroics with each level of badge. But then the complexity of balancing it all would take developer time away from NEW content, so I shrugged and accepted what I got.

I agree with you on the problem, but I'd offer a different solution: I think they should have toned down gear scaling. Judging by item level - and I haven't done the math by adding up and subtracting the stats themselves, but I'm pretty sure it would work out the same way - the difference between Naxx-10 and ICC-25 is just as big as between level 70 and level 80. That's a huge difference, especially considering that, unlike the endgame raids in vanilla or BC, ICC-25 is pretty accessible.

To be clear, I agree with that part, I like their current approach of making some version of the raids available to everyone and having the real challenge come in hard modes. But this approach has problems of its own, mainly the one you mention where current raiders can so ridiculously outgear content that was the beginning of the endgame at level 80. I don't think there should be so much gear progression within the endgame. (This would also mean that some encounters should have been tuned differently.)

I remember going into DM west one time back in vanilla WoW with a group of guildies, being cocky and getting sloppy because our guild had cleared most of AQ20 and BWL and some of us assumed that a five-man instance should be easy, and getting stomped once or twice until we started paying attention to the basics again. In vanilla WoW, no gear except for maybe the absolute best of the best could make up for not paying attention or knowing what you were doing. That's partly because things were designed differently, but mostly just because gear and stat progression was more gradual. Same for heroic instances in BC. In WotLK, though, all else being equal, one dps class in gear from ICC can literally do the work of two who just hit 80, and one tank can do the work of more than two. I hope this trend doesn't continue.

You don't make an old instance more interesting by giving the mobs bigger numbers. It's still the same instance, you've still done it a dozen times. It doesn't become more interesting, at worst it becomes frustrating. You don't want to make grinding emblems harder just for the sake of making it harder.

Creating entirely new, tougher dungeons with new boss fights is the way to go. And it's the way they went. And it was pretty cool. I still enjoy tanking tyrannus and finding ice patches over which he can hit me.

YES! For me it is hard to get on consistently enough to raid regularly so I miss a lot of that part of the game. Back in vanilla 5 mans were kind of their own progression and were big enough and hard enough to really keep you occupied for a good long time even though there was less of them at end game. BC did the right thing with introducing heroics, but the heroics now are sooooo easy that it makes me feel like I'm grinding.

That problem isn't because of gear. Its because of how much they simplified threat and tanking in Wrath. The idea of having more than 2 elite mobs beating on the tank seemed practically suicidal before AoE tanking took over.

I like the fact that the first post was not a "First!" post, that said, I couldn't agree more with your point. Content has been trivialized by the fact that we are overgeared for it, but I can also see this has helped plenty of us gear up for newer content alot easier which was blizzards intent. Come Cataclysm though I think your suggestion will definately go a long way in making players feel like they're actually making progress instead of just Farming the hell out of this easy heroic. Nowaday I'm just like you, Don't wanna run it cause I've already done it too many times.
