It's really just the shitty stats.
Camerupt is a great Rest user because it has a great offensive typing and only needs the two STAB moves in its moveslots for Sleep Talk, and it will have plenty of coverage already. Thankfully Earth Power/EQ and Eruption/Fire Blast hit most Pokemon hard. Fire/Ground also isn't as bad a defensive typing as it seems, especially with Solid Rock helping it tank.
Sharpedo has both great speed and priority, and it even has Close Combat and Psychic Fangs. Increasing its bulk will probably just make Rough Skin Sharpedo more popular, but won't accomplish much else. I'd bump defenses to 60 each.
