I agree. Even before 1.6, this (23/1/17) was still a solid build, especially for Huttball. For other maps, I would take the 2 points out of Instant Whirlwind and put them in Maul, to give you 23/3/15. Great to guard nodes etc until help arrives.
Everyone has been going on about 0/27/14 and although it is ok, surviving unless you have a pocket healer is difficult and most of the big hits come against badly geared folk. How that will stand up going forward is anyones business because I am not convinced that Infiltration is yet viable, despite have a massive(LOL) handful of seconds with blackout.
However, for burst damage, you cant beat full deception.
27/14 is a great spec for solo and non-serious rated play. I've been running 27/14 majority of the time since I've been back. However, 23/1/17 is still the best overall-based shadow spec in the game. Its versatility is still unmatched by anything else to date.
