Ski Durability

I'm about 7 days in to my first season of skiing (switched from snowboarding) and I've been hitting boxes and rails and such. It seems like my skis aren't holding up that well and I was wondering what's normal/to be expected when it comes to skis getting worn down. I've already had a "core shot" that was ptexed and one of my edges seems to be bent and separating from the ski. I ski 2010 armada alpha 1's that I bought here and I don't think i'm abusing them that bad for this to be happening. Thoughts?
