Feral 6.03 leveling questing macro. No addon needed.

Talents: Wild Charge, Ysera’s Gift, Soul of the forest
Glyphs: Savage Roar(essential), Cat Form, Ferocious Bite.

This macro is spamable, be sure to put it on the same key on both the action bar and stealth bar.

It will target the enemy then ‘wild charge’ them using ‘Rake’ to stun the target. (A modifier will make sure that ‘Rake’ always hits before you leave stealth ensuring the stun and ‘Savage Roar’ activate.
Whilst the enemy is stunned you will pop out of Cat Form to cast a ‘Renew’ on yourself then return to Cat form and finish them off with DPS rotation.

You will be getting healing from: Ysera’s Gift, Ferocious Bite Glyph and Renew, all of which are amplified by the Cat form Glyph.
