[Feral] PvE Opening

Hello fellow Kitties.

I've been playing Feral for quite a while now, but I still have some issues with energy-capping in the first seconds of a fight. I think my opening is standard, but even if I spam FB every 5CP , the GCD used to trigger the first manual DoC (when DoC spec'd, ofc) is enough to cap my energy, and I don't know what to do to. :(

My opening (assuming I use DoC):
• Pre-HT
• Pre-SR
• Pre-Pot

• Charge + FF
• Rake
• Shred
• SR (Maybe not optimal because I still have some time on it, but in average I have 3CP at this point, which gives me time)
• TF + Berserk (If Heroism is used at pull, I sometime cap here)
• Shred to 5CP
• NS + HT (Heroism or not, I always hit 100 energy here)
• Rip + refresh Rake

Any advice?
Thanks in advance!
