Unnecessary!!!
They should buff Harbor, this agent is the worst for a while
Stun is a small change. I will say that it probably should have been kept at 4s since you have to place the star, wait until it is set and then use it rather than just aim your stun like Neon or Breach. Stuns overall are kinda ass since you still get a lot of that "cosmetic stun" and enemies hit you just fine.
