After the update, spells seem to have much less damage than they did and the newly introduced lightning spells are doing so little damage that it is not even worth wasting your points on them. I have to use 5 fully charged first tier lightning spells on a regular zombie to take it down and that is when i had invested 3 points in the lightning spell talent. It doesn't matter if you are facing up against 5 zombies it is still not worth the effort. Fire spells aren't also that fine as well, i mean you can't neccessarily feel like a archwizard when you need to drop at least two or three huge ass meteors on a zombie biker to kill it. To be honest, for the late game i only used the teleportation and speed and jump buff from the fire spellcast.
