Moonkin with Feral ChargeFollow

I want Feral Charge as a Moonkin to successfully defeat many classes in 3v3. The main reason is that it makes ******** with enemies or at the least their AI-controlled pets/summons from DPSing me.

The main reason I saw for this is that I saw that Feral Charge completely helped me in duels versus a BM Hunter. If they use Bestial Wrath, I will get the max range from the Hunter for Charging, and whilst doing so, throw Insect Swarm and Moonfire. I then Charge, switch to caster, Regrowth/Rejuv, Moonkin again.

Screws with them all the time. I just need to keep a high defense up while keeping a distance from their pet as much as possible.

Without Bestial Wrath though, Hunters aren't such a challenge. If I use cooldowns... things are gonna hurt. I will abuse Cyclone, of course, and Bash... but I don't know about Barkskin and Force of Nature. I would use War Stomp if my RETARDED FRIENDS DIDN'T MAKE ME ROLL ALLIANCE! I hate Night Elves...

The main thing I see is that I'm going to miss Nature's Focus. Would that kill the build?
