Why not make "Hard" dungeons 6-man?

[Ryios]

Because the game is designed around 4, 8, and 24... When it would be so much better around 6, 12, and 36. And by designed, I mean the UI is built for a group of 4, not 6. They probably even have hardcoded code against 4/8 etc. It's like the frame of a car, once the car's built you can't really change the frame without rebuilding the car.

DPS ques would be about twice as fast with a 6 man group, because it would be 1 tank 1 healer and 4 dps, or 1, 1, 3, (1 support/dps).

12 Mans would just be double 6 man groups like 8 mans are double 4 man groups now.

CT would be 36 people, etc.

With 8 man groups there is no room for alternative comps unless you can solo heal it, or solo tank it. With a 12 man group you could easily add a healer, or 2, or an extra tank, etc etc.
