Don't use sequence macros.
You might wanna group Leap and Gnaw since a lot of times you'll use both at the same time, having a leap macro @party1 is a good ideea in that case.
"/cast [target=pet] Corpse Explosion" is a better macro for using CE.
Never use sequence macros in pvp.
You can add the self healing macro in your Death coil macro by going with a modifier so you'll have to use less macros.
And don't use sequence macros.
