Lol what utility? Scoundrels/ops have the least utility out of any class
Literally anything a scoundrel can do, a shadow can do better.
Shadow/assassin: Grapple, 2 sec knockdown (out of stealth if you're kinetic, which you should be anyway), 5 second stun, good damage, good survivability, guard, taunts, stealth, sprint, and a knockback
Scoundrel/op: Stealth, decent damage, mediocre healing
You'd have to be crazy to still be playing an op/scoundrel at this point if you're serious about pvping.
