Dungeon crawl-ish mmo?

Hey all,

I've been out of the mmo scene for a couple of years, but got the itch again. The game I've enjoyed most during my mmo "youth" would be Burning Crusade WoW. I did most of the hardcore stuff  in that game like doing 5-man heroics, grinding resist gear, and raiding 5 days a week (with forays into Kara/ZA on off-nights). Good times. I don't have time to raid anymore, but I'd really like to do some casual and hopefully hard content like 5-man heroics in TBC. Is there still a game like this somewhere?

To formalize, what I am looking for is:

- A game with hard 5-man dungeons. Think heroic Shattered Halls and Shadow Lab, slow 45-90 minute crawls with CC, wipes, and putting your own group together in trade chat. (Note: I am aware of 5-man challenge modes in Wow, but those things are about rushing though the dungeon with a cheesy comp, afaik.) Oh, and the game has got to have trinity, or something close to it.

- If I ever get out of 5-mans, a game where there are guilds raiding in every tier, so I can start at the button and move up. Again, think TBC: there were a few entry level guilds doing Kara, a few more doing TK/SSC, then BT/MH, like a ladder. (The opposite would be current WoW, where every guild ends up doing the latest tier as it comes out, because of free gear and LFD/LFR).

A  game that has some of these features would be great. Although, I am interested in meaningful 5-mans first, and raiding second (something to do maybe if I complete the 5-man grind). Anything in existence that sounds like this? I know WildStar promised some of these things, but I am looking for a game that is out right now.

~thanks!
