Fastest way to level dungeoneering?

I got dungeoneering to level 18 or so when it first came out and it just got really repetitive and boring. I've been looking around though and people say its the fastest skill they have been able to level. Whats the best way to level dungeoneering?

 

Get someone else to do it? There's some guy running a dungeoneering service, I think his name is Crab or something like that.

 

- Enter dungeon
- Unlock all rooms
- Kill all monsters
- Kill the boss
- Repeat
- ????????
- Profit.

 

Sadly, crab recently stopped because the glitch he used to level so fast had been patched.
