The Shadowed Strike (30% damage while cloaked) perk increases the damage of every round in a burst. A two shot burst VOT fragger will have the bonus on both shots. The same with a burst AR or the burst LMG.
Try using purely defensive perks. (30% less damage from behind, half damage when shield breaks, etc.) to improve your survivability in pvp.
Also, a high health shield rather than a Respark would help prevent them killing you with the alpha strike.
It holds true in most pvp that survivability/dodge beats damage.
