Scopes and I were planning on making the grenade case so that it can't spawn in if the player is a round start antagonist such as Changeling, Nuke, starting cultist/traitor. If they become an antag at some point throughout the round, then there's barely an advantage in starting with it because the player would have no rhyme or reason to consider using them for antag things until they become an antag. If we find out that they were gearing up the custom grenades in case they become an antag, then that's metagaming, and he loses his custom item. Any other concerns?
