I dunno, the real damage from grief is in the +389 damage modifier. I would have tested it on a smiter maybe.
Yea, I think you're right. You can smash anything with any grief on a smiter pretty much. Oh well. I mean PB will still be better of course, but the CS would still be able to kill ubers, just a little less efficient, and not indestructible, so repairs are frequent. Hindsight is 20/20 I guess.
