I hesitate to offer advice as I rerolled for pvp. So take what I say with a grain of salt.
It's not so much a problem with stuns or silences, it's the stun into a blanket that has a high mortality rate.
There is a greater onus on you to avoid getting stunned in the first place. I found I could play a little sloppy given the tools I had.
As PPN said, your teammates should expect the stun --> silence and be prepared to peel for you. You can try to squeeze a SWG in between the stun and the silence for the 4-piece bonus.
Talents? Nature's Guardian was already attractive. Probably the clear winner now. May make Primal Elementalist more attractive. If you can see the storm coming, Earth Ele gives you a self peel and another defensive CD.
