It's not shoulder charge. It's in air shoulder charge. With the exotic boots it can pop anyone and anything with one swoop, even those rammy warlocks with radiance. With arc burn and brawler it can drop valus to almost 2/3 of his hp with one charge. Almost every super can pop a bubble and kill those inside it is reasonable because it's a defense ability. It'd be way too op if it didn't have any risks. It's the same with all other supers. They can be stomped too.
