According to most players that does gain lots of exp dungeoneering each day; they use 'Pro teams' and stick to that team forever. until all of them are at 120.

 

I'm quite interested in one myself. As you may see on my signature, i'm an avid 'Scaper. and would like to get the last 10 Dungeoneering levels quite quickly.

 

Any suggestions on how i can find a team like that? (I'd love to get a Completionist cape before the new skills come out)

Try DG Addicts. You'll have to apply on the forums.

You don't just go out and find pro teams, they find you. For the most part, particularly now with shared keys etc, floor times are very much dependent on a leading dungeoneers skill and thus you can average good times even with only 3 dungeoneers doing all the work. Thus it'd be advised to learn and get better at pathing and leading a team first, then finding and accumulating good dungeoneering contacts to achieve fast experience. I'd suggest DGS but unfortunately your goals are set way too low.

Pro teams are a pretty big commitment for everyone involved, remember that they're choosing to dungeoneer with you instead of anyone else, so you need to know what you're doing already. They're brilliant if you can get one, but you have to earn it through experience, skill and social contacts.

 

Best place to start is with clans. First place to look would be a dedicated dungeoneering clan. They vary a bit, some prefer high-efficiency Dungeoneering (DGS comes to mind) and others go for a more relaxed approach (Chilled DG comes to mind), so try looking around to find one to suit your play style. Make sure you're open to learning good techniques, pathing, and the abbreviations, which most dungeoneering clans will teach you.

 

Alternatively, try looking for a more general skilling clan, which will almost always have a Dungeoneering division. Often, that division is small enough that it's virtually equivalent to a permanent team.
