With the PTR now available for public consumption, we hunters can now test some of our new abilities...and more importantly, Focus.
My personal impression? I feel like a complete noob again. I've especially had problems with the idea of Arcane Shot becoming a focus dump. I'm just not used to the idea of being able to use an ability but actually having to show restraint! Practicing on a dummy, I found it extremely difficult to use Chimera Shot/Explosive Shot when the cooldown ended because I had used all my focus on Arcane shot. Either that or I barely used Arcane shot and became focused on watching for when the cooldown on the other shots ended. This will take some learning...
Unfortunately, I didn't get to use multishot on groups of mobs yet, as the PTR client crashed as I was flying to my destination. So what does everyone else think? It should certainly make the same old boring ICC run a little more interesting when it goes live!
