I don't really know any warlock abilities, but this ability needs some fixing. It can basically track you infinite distance and you can't destroy it before it reaches you. Then you get hit with weaken and burn damage on top of that. The tracking and range is too strong. I've literally watched this thing leave one target that died before it hit and travel across an entire map to nail me. Can we at least get the chance to shoot it out of the air or something before it can reach us? That seeker is just too strong.
