Currently last ascent version has no cooldown in throw weapons, bug of course.This works on 2.2.3 server, so it should work on lower version I assume.
Make this macro:
PHP Code:
/cast throw
/stopcasting
/cast throw
/stopcasting
/cast throw
/stopcasting
/cast throw
/stopcasting
/cast throw
/stopcasting
/cast throw
/stopcasting
/cast throw
/stopcasting
/cast throw
/stopcasting
/click ActionButton9
/click ActionButton10
Throw weapon in action bar 9 and this macro button in action button 10
