I killed a guy with my hammer and he exploded killing a guy that was maybe 3 feet from him and THAT second explosion killed a 3rd guy that was about 5 feet from the second explosion. That's the most overpowered chaining effect I have ever seen. A little nerf is necessary for crucible at least, but not for PVE. Although I disagree with the armor being nerfed. You have no idea how many times I've been gunned down by red death and such.
