Melee - Cata/Mop - Swing timer

Hi folks

after playing SoD twisting where its all locked to the Swing timer, Can someone left me know if a weapon swing timer is still relevant in Cata going into MoP?

like the main thing in SoD is pressing an ability too close to your melee swing, scuffs your twist damage,. is this an issue in Cata/Mop? does pressing CS too close to my swing going off, cancel my swing damage?

It is not! You are free. Only cass that checks swing timer is enhancement shaman to not clip an attack while hardcasting with 2/3 malestrom charges. In MoP I think Slam in warrior is instant

nice thanks! can ditch the swing timer weak aura
