there are some faults in your logic. lets start out by looking at Surging Charge, you essentialy switch Force Pull out with Surging Charge, but you do not pickup Induction in the deception tree, wich you abosolutly need to take if you're going for anykind of deception build/hybrid, so far the the trade you've made is not an equal trade, and discharge of Surging Charge without all the support talents is very weak.
Also you decided to go 3/3 in Shroud of Darkness, seeing as you're talking about beeing bursty dps you''ll be full stalker so you're hp will be around ~17-18k depending on gear lvl (assuming you are wellgeared), again the benefit from that is so small, that you would proberly be better off with a on demand heal from Hollow.
As for the Madness tree you've decided to go w/o Torment wich would proberly be one of your very best talents, seeing as you build is focused on Trash, another big mistake.
Overall I understand that you want to try something uniqe, but you're basicly leaving out all the talents that are great to gain underavg. replacements for them, and by underavg. I mean that you're leaving out all the support talents that would otherwise make them great. And with the specc you posted you gain nothing but reduced performance.
If you want to burst, and I mean really burst then theres 2/31/8, and to some extend 0/13/28. Otherwise a "bursty" tank build with a ton of utility/survivabilty would be 23/1/17.
Any way thats my thoughts on your build/thread, use or dont
