You want a cat rotation?
ok then, example for a radi boss fight
Rotation 1.
beserk, Ravage, shred, shred, SWITCH TO BEAR FORM enrage, spam mangle and maul till beserk is gone (u can queue maul, and still spam mangle ^^ extra dps ftw) SWITCH TO CAT FORM, rake, (hopfully u have 5 combo with procs now), FB BOOM 14K CRITS !!
Rotation 2.
mangle, shred, shred, bear form do magle + maul and another mangle, shift back, rake, tiger fury (100 eng ftw), FB BOOM 14k crit again
u get the picture? remeber to use FB on bleeding targets, it pawns and boost ur crit chance by 50% i have 38% crit chance in cat form raid buffed + 50 = 88% i rarly don't crit it
remeber to use the right glyph
