Symptom : 

Swing timer stops at current swing time during "Slam" use, and resumes after it.
Swing timer not reset to 0 after warrior "Slam" use

Expected :

Swing timer stopping during cast (why not) but Swing timer reset to 0 after warrior "Slam" use

Explanation :
warrior "Slam" counts as an auto attack and should reset the swing timer to 0 (the same as after an auto-attack)

Tested with All addons but quartz desactivated.
using Improved Slam 2/2

the issue is still up and makes Quartz useless for Arms warriors. Please fix it :)

as mentioned above - slam resets the autoswing timer.
