When we queue spells while holding shift the backswing is very annoying, the heroe waits sometimes one second or more with the cast point + backswing. It must be removed because it makes the queuing only usable for items. For example with Queen of Pain after blinking, the scream of pain will wait 0.63 seconds before casting another spell or auto attacking. I think this will only result on players using more macros to have the perfect timing.
