it depends on what Pokémon you use. if you use emboar, I guess its OK. I would honestly not recomend it though. there is so many better moves then that. if you were talking about other weight affected moves I could help you more. like for instance, give an aggron heavy slam with heavy metal and its the heviest Pokémon. but if you ask heat crash, I still say I need to know what Pokemon you plan on working with.
