Erm... You do know these grenades only take out half of your health, right? You'd have had to have been shot before getting naded, so you can't be all that good. Arc bolt and firebolt are both weak grenades that are used only as easy followups and easy instant damage. They're easily avoided under the right circumstances and are both much weaker than the lightning and flashbang grenades. I thought you might actually be raging over the fusion, flux, and magnetic grenades, and even those are underpowered.
