There are two problems to shiver strike which I've faced consistently. 1. Shiver strike not working in close quarters when I'm pressing powered melee. Mostly in pvp, I've come across a problem in when I press my charged melee I don't use shiver strike and just do a generic unpowered melee. The problem may lie in that block and powered melee are both bound to the same key but since you cant even pull out a sword in crucible without ammo. This shouldn't be a problem since it says that block only works with swords and certain pickup-able items. 2. Shiver strike damage applying way too late. I've shiver strike'd people in pvp but it doesnt deal damage during the animation and I get double melee'd or shotgun'd by the same guy. Perhaps this is intended but it feels really bad to shiver strike a guy within red health in crucible and just lose because he has a shotgun and your damage is not applied after. Minor issues: Shiver strike sometimes not generating stasis lance when killing someone. Shiver strike and super melee just launches people. I've had my super melee launch a dawnblade warlock from fountain to the end of district.
