Standard Madness builds do a little less DPS than deception, I believe. However, playstyle can negate that sort of thing. I believe it's also easier for a sorc madness to unleash their dots easier to hit players harder.
If you have a really good healer on your team, having full deception is useful, otherwise, I'd still stick with the afformentioned build (23/1/17) though. Essentially what I'm aiming for is like having mini smashes but not having to wait under 12 seconds per smash, and also having some self heals to increase a bit of survivability.
Is the 23/1/17 good for levelling?
