An extra life is about the same worth as a super that when used correctly can wipe an entire team. Arc Blade has Aim Assist, Hammers have splash damage, so of course it's not balanced to give stormcaller something that allows it to be used in close range. It's totally not balanced that the best grenade in the game needs two modifer for it even to be a contender for top 3 grenades. Hey my Sunsinger melee requires a modifier to burn as long as the Sunbreaker one. But hey, balance. The class with the most armor is also the fastest moving. But hey, balance.
