Edit: His comments in response to some questions I asked:
Yes I am using every special ability as soon as they come off cooldown while using Steady shot to refresh my focus. The play style feels like the live server if I had an unlimited amount of mana. I don’t have to worry about switching between Viper and Dragonhawk which allows me to focus more on other things like say my pet or other shots not in my rotation. I also don’t have to worry about how much ammo I have or having to craft more after a raid is over. That change I love.
I also took all the talents that have some type of focus regen on them which it seems most hunters would take anyways to get further down the tree, which is why it probably looks like a mess. Concussive Barrage adds a nice little dps boost along with its follow up talent. However, all of that is going to change so I will have to tell you how it works after they revamp all the trees down to 31 talent points each.
Steady shot does damage and has a focus regen modifier to it. So you would spam that while weaving in your specials including arcane shot when it is off cool. The hunter rotation has more of a priority to it now. So if Chim and Arcane are both off cooldown and I only have focus for one, I cast Chim and wait for focus to cast Arcane while Chim is on GCD. I didn’t have to wait long. Steady Shot and the other talents regen my focus so fast I could just sit there and spam my button as fast as I could press them.
I didn’t talent my pet yet, I was just focusing on show that my hunter was not focus starved like many people keep saying they are.
