Is it just me or does frost wall not block porcupines' spike novas anymore? I have it linked to my usual level one CWDT; it procs, and I'm seeing the wall go up; but the spikes are still going past the wall. Was this an intentional nerf or a bug?

My frost wall doesn't work at all. It's behaviour is erratic, sometimes it blocks some projectiles, sometimes it doesn't block anything, not arrows, not monsters passing through. It always blocks my projectiles though. I'm waiting for a new skill gem to drop to see if it's related to my gem being older than 2.0. Other than that, I'd say it's bugged.
