for me Chou,Jawhead, and Martis and bane idk
1. chou his CC skills and an ability to throw enemies to the turret(if you can actually throw them to the turret)
2. Jawhead good cause of his ult and throwing ability
3. Martis cause of His CC and high damage and sometimes enemies can just flicker or teleport their way out of his Second Skill(Mortal Coil)
4. bane idk his damage is good but assassins can escape his ult
Martis is balanced, has a great HP and has great number of CCs in his skill. He can kill an Assassin or grab the assassin's attention until backup arrives.
Depends on the assassin. If they have CC (selena, helcurt and saber), pick Martis or Chou for immunities. But if they have high burst damage (Lance, Haya and Gus), pick Jawhead or Bane for extra healing/shield.
Bane is fast killer because he has ridiculous burst damage
