Also.. Dodgin castbars takes a lot more practice. Look at Castrum Licas Litore for an example, the ORder mechanic with the crosshairs... There isnt even a castbar and people die from crosshairs ALL THE TIME.. despite the fact that they KNOW how the mechanic works...
Because you cant see where the "snapshot" happens. Which makes it enfuriatingly frustrating and you get the whole "F this I dodged that mechanic and i know it!!" situation....

Just dodge the actual animation, and PRESTO.. frustration gone!!
