Yes skip grenades need to be nerfed. Most players use Viking funeral as an offensive tactic. One shot to the body with a scout or hand cannon, and chuck a firebolt at them. Then watch them burn out. Every warlock I run into nowadays runs tlw, and shotgun. It's either slide, shotgun, melee. Or firebolt from around a corner and rush in and finish off. If I'm to avoid any of that I'm gonna sit back and hard scope a corner every time I see something on my radar. Viking funeral give a warlock 10+ seconds to finish of enemy. All the need to do is deal about 40 damage to them.
