this looks like a hint from the devs that there may be a real combat routine for tank mages in the future. One where your wizard uses the power of walk when casting on a target. This could make frost nova/explo finally work and fix alot of line of sight / stuck problems. too bad its not more than the deathtrap startup option of demonbuddy atm, where you can end up with millions of repaircost and hundreds of deaths when clicked.
