over the course of finally getting around to playing PVP, i have learned something rather fantasticly exploity about the Lightning balls of death ultimate that is the Sorcerer Overload.
If you tab target another player with it, and keep crosshairs on the box, you will be able to attack and hit them even through walls until you lose the lock or kill them..
i have several kills who i just tab targeted and then got behind a wall and shot overload light attacks through at them until they died... People on top of a keep who peeped through long enough for me to tab target them, who died running down the stairs to of the inner keep trying to get away from the ghost balls of lightning...
so ya... nice new bug info for people to read about, and exploit until they patch it.
I play every class in every situation. I love them all.
