Umm... which DA? A, B, C, or D office? I know I personally went in w/ an awesome crew in D office. Puzzles completed very efficiently, all cogs before elevator were taken out in one round, and the end cogs at all the elevators only took 2 rounds. 30 minutes, and my friends all have to ask me 3 times to make sure I said it was only 30 minutes. It can't be done any faster than we did it - there couldn't have been any better effiency than if I went in w/ all SF's.
BTW, all had sound (2 ele, 2 fog used for each in-between set of cogs), I used (organic) lure for each end set, all 3 other toons had trap, and 2 had drop - and 1 had an organic b-day cake to use on the right-most cog once or twice. NO virtuals and the puzzles were solved in a matter of seconds
edit: I should say "I can't see it possible to do it faster"... perfect coordination the whole way through
