That does look a solid build, the only comment i would make is as a triform and the kheldy sets soooo large you might wanna focus more on some of your own powers rather then going into the health pool as the bonuses don't carry through to the other forms.
Oh and just saw, personal choice, but i put a recharge in my Dwarf's antagonize rather then an accuracy, in case someone is in trouble and I've already dropped it. Every second helps lol.
But other then that, i think you've got a really good build. Only got a 21 WS myself, so maybe someone will point out something i missed or go wrong.
Gd luck and enjoy your squidy
