All around good opener!

Little something I been testing out. Add this to your feral dps macros for opener

/castsequence reset=target !rake,Rip,null

For example

PreMacro=[[
/cast Wild Charge
/targetenemy [noharm][dead]
/use [noform:2]Cat Form
/cast [nostealth,nocombat] Prowl
/castsequence reset=target !rake,Rip,null
]],

Much love to Sandra Primm. Added the macro to their. Pretty satisfied.

This is what I came up with using your pre-macro

Sequences['Collin'] = {
author="Demongior@Tichondrius",
specID=103,
helpTxt = "Talents: 2331212",
icon=132115,
PreMacro=[[
/cast Wild Charge
/targetenemy [noharm][dead]
/use [noform:2]Cat Form
/cast [nostealth,nocombat] Prowl
/castsequence reset=target !rake,Rip,null
]],
"/castsequence reset=target/30 Rake, Shred, Shred, Rip, Shred, Shred, Shred, Ferocious Bite, Rake, Shred, Shred, Rip, Shred, Shred, Shred, Ferocious Bite",
"/startattack [noharm,combat]",
PostMacro=[[
/startattack
/cast Tiger's Fury
]],
}
