A bladedancer with stealth perks, hungering blade, Khepri's Sting, an FA shotgun, and a decent distance weapon can leave you in the body bag and be gone without a trace. A gunslinger can trigger his Super and burn off the heads of an entire enemy fireteam before they know what happened. And with the Achlophage whatever, he can even miss a shot. A voidwalker with Bad Juju, Obsidian Mind, and maxed Intellect can drop an endless stream of void-powered annihilation. A sunsinger can stand up and incinerate you while you're still teabagging his corpse. A defender with Ruin Wings, Kellslayer's Greaves, a Gjallie, and an Iron harvest perk can lay waste to the enemy, while protecting and powering up his allies so they can unleash MORE devastation. And a striker, with certain well-chosen equipment and perks, can hammer his adversaries with an essentially endless number of one-hit kills, then drop himself on your team when you're waiting for the heavy ammo to spawn and send you all to electrical oblivion. Consider all classes defended, period, exclamation point.
