Ok, not nerf entirely, but I do feel that there should be at least a tiny delay between uses, or in disarming it. No reason, IMO, disarming two bombs 10 - 30+ apart should be do-able in < 5 seconds. Honestly, whether strategies using C4 are good or not, etc as some may try to argue about is irrelevant, it just feels overpowered *as it is*.
