They generally don't. They pay for their independence from mana costs in other ways - completely resourceless champions tend to have long cooldowns, energy champions have a fixed low cap which drastically limits how fast they can cast their spells, and health champions can effectively slowly kill themselves as they use their spells. Rumble is much like the energy champs in that it's best for him not to spam his spells repeatedly, but there can be a situation that calls for him to silence himself on occasion.
