Crit chance in PvP

Is it just me, or does horde have some sort of hidden resilience? I have 30% crit chance in my PvP gear, and my abilities almost NEVER crit. I can beat on a priest for a solid 30 seconds and not get a single crit from a yellow hit.

I’m a feral druid (yes yes, i know) but that doesn’t take away from the fact that my shreds seem to have less than 5% crit chance against horde players.

Anyone else experience this or do i just have the worst luck ever?
