curious as to the actual (without lag) cast delay of spells, and for some of the spells the delay on targeting then dmg , i.e - FS and ebolt. there's like a moment delay before dmg is actually done after targeting.
i'm sure the gm's got the exact numbers, and if ya'll do or know where i could locate this info that would be awesome, that is if you wish to share it
if your asking how long u have to wait to cast a spell immedietly after, (which as u stated can be removed by holding the target) then what you want to do is record razor macro to cast the two spells you inted on casting in a row, then slowly increase the wait between each spell.. once you've found the right timing, you'll know cuz it'll cast the two spells quickly
