Describe the bug
At the moment the swing timer doesn't seem to catch the wind up of the first swing because it's watching SPELL_CAST_SUCCESS I think it might be better to watch SPELL_CAST_START too, to get in the wind up of the swing for ranged weapons.

Additional context
I believe that this is for some kind of hunter min maxing thing. Either way I think it would be a nice change to the swing timer, or at least adding the option to swap between the two.

Nah, this doesn't really make any sense the more I look into swings in classic.
