Thoughts on my Grav/Time build?

[icesphere]

So i was going around and trying to find what moves I want along with the way I like to play. I'm trying to go with this makeshift build that works around Crushing Field and Wormhole, while also getting holds and procs thrown in for fun. I hope I did okay, I don't have a whole lot of defense myself, but the build was supposed to be more around helping the team and debuffing the others while I stay in the back and, hopefully, don't get noticed. Any thoughts or advice is appreciated.

I'd say have a look at Redlynnes Grav / Time thread

 

and the thread here for ideas : 

 

As there's quite a few ideas & builds in those for Grav/Time. Having a quick look at your build it seems expensive but fragile (purple sets and Hami-Os can be dear). Power Boost in the Primal Epic is worth stretching for as it makes Farsight basically take care of a huge chunk of your defenses for you.
