It's not really lag, it's just that spells won't put you into combat until they actually land. This isn't a problem for things like shocks/chain lightning that have little to no flight time, but when you're at max range firing off a lightning bolt, it will take some time for hte lightning bolt to reach it's target (especially if it's running away from you), and I didn't want to waste mana on an extra ToW just because I was too over-eager with the button mashing.
